[00:00:33]Hey guys, good evening. Good evening and welcome back. Welcome back. Welcome back.

[00:00:39]Let me know once in the chats if all of you can hear me. If I am audible, visible to everyone of you. Let me know quickly in the chats.

[00:00:52]Let me know quickly in the chats if all of you can hear me. If I am perfectly audible, visible to every one of you.

[00:00:57]Quickly my dear students.

[00:01:07]All right people.

[00:01:10]So as you all must be knowing there were a lot of students continuously asking that please take a demo session of the Phoenix 2.0 batch which is getting started on May 20th. Right?

[00:01:27]So therefore I'm here in front of you and here I will be taking a small session of almost like 25 to 30 minutes not more than that. Okay. I'll give you a proper demo of how classes are going to work, how we are going to teach in the Phoenix 2.0 with the amazing neat English team, my dear students.

[00:01:47]Okay.

[00:01:49]Well, those of you who do not know what this Phoenix 2.0 batch is all about, let me quickly tell you first of all this Phoenix 2.0 batch, it is basically a dedicated batch for NE 2027 aspirants.

[00:02:05]Whether you are going to write the neat examination for the first time, second time, third time does not matter. In this particular batch, we are going to complete your entire syllabus. My dear students, let me quickly show it to you.

[00:02:16]Your entire syllabus here in this particular batch will be completed till till December end. Point number one.

[00:02:26]Okay, this is the dedicated batch which is getting started in English language dedicated for NE 2027 aspirants. The bath start date is 20th of May. Well, after completing your entire syllabus in December, the remaining two months that January and February, we have kept for revision and in the batch itself. Okay.

[00:02:47]Again, you need not to worry about the study material. We are going to provide you the level up study material in this particular batch.

[00:02:54]After every live session, you will be given the DPSPs, the daily practice problems which you will be able which you will be solving. Those DPSPs will be again the level of DPPS. my dear student right and no need to worry about the noun solving perfect and at the same time my dear students there will be tests after every 14 days and there will be test paper discussions as well and these tests which you'll be writing there'll be again the level of test because we never know what's going to be the level of the 2027 examination it can be tough also so we are going to get prepared for the worst okay that is something which we have in our mind at the same time every single day you'll have three classes the duration of each live class will be 1.5 5 hours.

[00:03:35]There will be recordings provided to every single student after the live session. You'll be having the access to the recordings as well. And my dear students, as I keep on telling you, you are getting trained by the best of the best in this particular batch. I will be taking care of your complete physical and your organic chemistry. KK sir will be taking care of your organic chemistry. Y sir, he'll be taking care of her complete class 11th, class 12th.

[00:03:55]And Tina ma'am, she'll be taking care of her complete biology, my dear students.

[00:03:59]Okay. Perfect. and and and and at the same time there are few more important things. What is that? My dear students, if you are enrolling into this particular batch, you will be having the access to all the batches of an academy completely free of cost. I hope I have told you that earlier as well.

[00:04:22]So basically what we are going to do is in our academy we are not starting only this particular batch there are different batches created by different teams and you know all these teams I'm pretty much sure me and my team we have started a batch for NE 2027 aspirants in English language seat ma'am with her team they have started their batch in English language similarly Gimma ma'am and her team they have started their batch in English language pratik sir has started his batch in English language I mean in hind in English language right you'll be having the access to all these batches absolutely free of cost right so this is one special thing which you do not get anywhere else my dear student so this is a special feature which you are getting at an academy so if you are enrolling into the batch into my batch for example automatically you'll be having the access to all the batches of an academy absolutely free of cost okay yes it's a first live demo session right wherein I'll showing you as I keep on telling you every single chapter will be started from the basics from the scratch. So here in this particular session I'll show you exactly how the chapters will start from basics. Right?

[00:05:30]And the duration of this session is going to be not that much since it's the first session. So I'll just keep it for 30 to 40 minutes. Right? And my dear students till we start the batch actually the batch is starting on 20th of May. We'll keep on having these small small sessions so that you remain in touch with your books with your syllabus basically. Okay.

[00:05:49]Got it?

[00:05:52]Got it people?

[00:05:56]All right, a lot of people are saying how do we enroll into this batch. My dear students, the video which you guys are currently watching, this is the live session which you are watching. In the description of this video, there's a link. I'll pin the same link in the comment section. You just have to click on the link and after clicking on the link, my dear students, you'll get automatically directed to this particular page. Here you have got two options. Either you have to take plus subscription or you'll be taking the iconic subscription. Now my dear students what is the difference between plus and iconic? In plus the study material in plus subscription if you are taking the plus subscription of an academy the study material the study material which you'll be getting here that be provided in PDF format and if you are taking the iconic subscription the study material which you'll be getting you'll be getting in the form of booklets and those booklets will be delivered to your houses. Again if you are taking iconic subscription you'll be writing the tests in offline format. So basically all these tests will be uh given to you with the OMR sheets everything. So you can try writing those tests in the offline format as well.

[00:07:00]Okay. And in your iconic uh subscription there is one more important thing. What is that? You get more frequent one-on-one mentorship sessions. More frequent one-on-one mentorship sessions my dear students. So basically in both the subscriptions you get mentorship sessions with us but in iconic you get frequent you get frequent mentorship sessions in iconic subscription. Okay live session timings there are different different timings. Let me quickly show the timings to you as well. Let me quickly show the timings to you as well.

[00:07:30]So my dear students first of all this is your complete biology course flow right?

[00:07:34]Which chapter is starting on which date and how many lectures are allotted to a particular chapter. As you can see as you can see this is your biology course flow. Similarly, this is your physics course flow, right? In how many sessions Yavasar will be taking a chapter, completing a chapter and the chapter starting dates, every single thing is mentioned here. Every single thing is mentioned here. Similarly, in my subject in chemistry, there's the complete course flow, right? In how many sessions I'll be completing what all chapters for example mole concept and concentration terms I'll be completing in 12 sessions, right? And duration of every session will be 1.5 hours. Perfect. Similarly redox reactions our next chapter I'll be giving eight lectures to this redox reactions and again duration of this every lecture every live lecture will be 1.5 hours similarly nomenclature 12 lectures atomic structure 10 lectures thermodynamics 10 lectures general organic chemistry 10 lectures similarly my dear students if you go to chemical equilibrium right some 12 lectures perfect so everything is properly planned here in this particular batch right everything is properly planned here in this particular batch and at the same time this is your test flow right for example your test number one is happening on 14th of June minor test one this is the syllabus for biology here this is the syllabus for physics here and this is the syllabus for chemistry I believe all of you can see this properly so everything is properly planned right and this schedule will be given to you prior and my dear students these are going to be the timings these are going to be your timings of different different classes perfect as I told you every single day you'll be having some on an average you'll be having three sessions every single day just on one day right just just we are increasing the number of classes for biology biology class might be increased because one teacher is taking care of both zology and botney so biology classes might get increased in between okay perfect people and these were some amazing students last year who were with us in the Phoenix batch in the Phoenix 2.0 my door bags last year and they have done it.

[00:09:35]Now it's going to be your turn to show the bullseye with all of us. Yeah. So should we start people? Should we start?

[00:09:44]Should we start? Should we start? Should we start all ready? So all those students who did not get enrolled yet right do get enrolled people quickly as soon as possible. I was showing you how to enroll. So after clicking on the link for example if you are doing the plus subscription here you have to click for 12 months. If you're taking a total 12 12 month subscription, click on continue and automatically you'll be directed to this page. Here you have to put your mobile number or you can continue with your email id and right now this batch you are getting only at 469 right but this is the offer only till today 469.

[00:10:14]Tomorrow it cost will going to is going to hike up for sure.

[00:10:18]Okay sir your class is a little bit stucking I think there are some internet issues which I'm facing currently. Let me check once. Let me check once. Let me check once I can frequent get frequent mentor iconic subscription.

[00:10:44]>> I think it's perfect timings. There are different different timings. Let me quickly show the timings to you.

[00:10:53]I think it's perfect now.

[00:11:05]Just give me a second. There might be some internal issue. Let me just get it done. Just give me a second, people.

[00:11:19]I think my internet pack is over.

[00:11:22]Just a second.

[00:11:28]I'm just recharging it right now.

[00:11:55]It might take few seconds.

[00:12:59]Check my dear students. Is it fine now?

[00:13:01]Yes. Yes. My class are starting on 20th of May. Just check once. Is it fine now?

[00:13:11]It should be fine by now.

[00:13:14]Check my students. Is it fine now?

[00:13:31]All clear.

[00:13:37]Perfect. Perfect. Perfect. Quick, quick, quick. Everyone in the chats.

[00:13:44]All right. So all those people who would want to get into the iconic subscription who would want to take the iconic subscription again here instead of plus you have to take iconic and you have to click on continue and after continuing my dear students you are getting the iconic subscription as well and the cost of iconic subscription is 149 perfect but you know there are some additional features here in this iconic subscription if you take this study material everything right your notes everything will be provided to you in the in the booklet form basically and they'll be delivered to your All right. So all those students who did not enroll yet, I would highly recommend you to enroll quickly as soon as possible because the pricing of this particular batch will be increased day on day.

[00:14:31]All right. So let's get going then.

[00:14:32]Let's get started.

[00:14:34]Let's get started guys.

[00:14:38]My dear students in this particular session what I'll be teaching you I'll be teaching you some very very very basic stuff as I told you every single thing will be started from the scratch from the basics okay in your first chapter of chemistry that is your mole concept in your first chapter of chemistry that's your mole concept I will be teaching you a basic term but you are going to for sure get a feel out of it Right? Try to understand what exactly I'm going to do.

[00:15:11]My dear students, I'm marking the heading here as this is one of the basic terminologies which I believe every one of you would have heard once in your life for sure.

[00:15:25]And what is this basic terminology? It is your atomic mass.

[00:15:31]My dear students, what is the basic definition of atomic mass? How do I define the term atomic mass? How do I define the term atomic mass?

[00:15:42]Atomic mass in simple terminologies is defined as the mass of one atom of an element.

[00:15:58]Atomic mass is defined as the mass of one atom of an element.

[00:16:04]Now if I ask you how many different elements do you have in the periodic table? Your answer will be in the periodic table there are there are 118 elements. Right? In your periodic table there are 118 elements you must be knowing about.

[00:16:21]Now my dear students just select any element of your choice. Just select any element of your choice.

[00:16:29]I'm selecting for example the element nitrogen. One more element I'm selecting that's oxygen. One more element I'm selecting that's florine. Or how many elements I selected? I selected three elements over here. One is your nitrogen, oxygen and florine. Three elements. My dear students, imagine that I have got one atom of nitrogen with me.

[00:16:52]Imagine that I have got one atom of oxygen with me. Imagine that I have got one atom of florine with me.

[00:17:01]All right. I took three elements.

[00:17:04]Nitrogen, oxygen, florine. I have got one atom of nitrogen with me. My dear students, as per the definition, as per the definition, the mass of the mass of one atom of nitrogen, the mass of one atom of nitrogen is something I will be calling as the atomic mass of nitrogen.

[00:17:25]As per the definition, the mass of one atom of oxygen is something I'll be calling as the atomic mass of oxygen.

[00:17:35]The atomic mass of oxygen. Similarly, as per the definition is concerned, the mass of one atom of florine, the mass of one atom of florine is something I will be calling as the atomic mass of florine. So what is atomic mass in short? Atomic mass is nothing but it is the mass of one atom of an element. For example, I'm asking you what is the atomic mass of sodium.

[00:18:00]If I ask you what is the atomic mass of sodium, what does that mean? That means I'm asking you the mass of one atom of sodium. If I ask you what is the atomic mass of boron, that means I'm asking you the mass of one atom of boron. If I ask you what is the atomic mass of magnesium, that means I'm asking you the mass of one atom of magnition. So in short, I would say the mass of one atom of an element. The mass of one atom of an element is what we call as the atomic mass of an element. As simple as that, right? As simple as that. I believe this is clear.

[00:18:32]Now my dear students, if I go into the details of this atomic mass, if I go into the details of this atomic mass, try to understand very carefully what I'm going to say.

[00:18:43]For example, for example, imagine that I am taking two objects over here. Imagine that I'm taking two objects over here. Object number one, object number two.

[00:18:56]My dear students, let the weight of object number one is 5 kg.

[00:19:02]Similarly, let the weight of object number two is 10 kg.

[00:19:08]So here I took two objects. I'm assuming that the weight of the first object is 5 kg. The weight of the second object is 10 kg.

[00:19:18]Now my dear students, can I do one thing? Can I write this 5 kg as 5 * 1 kg? I can do that because 5 * 1 kg is equal to 5 kg. Similarly 10 * 1 kg is equal to 10 kg. So what I did I took two objects the the weight of the first object is 5 kg. The weight of the second object is 10 kg. Right? I broke this 5 kg as 5 into 1 kg. I broke this 10 kg as 10 into 1 kg. Now my dear students can I say just one thing? Can I say this particular object this particular object is five times heavier than 1 kilogram?

[00:19:58]Yes, I can say that. Can I say this particular object is 10 times heavier than 1 kg? Yes, I can say that. The first object it is five times heavier than 1 kg. The second object that is 10 times heavier than 1 kg. For example, my weight is 85 kg. What does that mean?

[00:20:17]That means I am 85 times heavier than 1 kg. For example, your weight is 60 kg.

[00:20:23]What does that mean? That means you are 60 times heavier than 1 kg.

[00:20:28]Correct? So, can I say just one thing?

[00:20:30]Can I say I am comparing the weights of different objects? I am comparing the weights of different objects with what?

[00:20:37]With 1 kilogram.

[00:20:39]I'm comparing the weights of different objects with what? With 1 kilogram.

[00:20:43]Right. This 1 kilogram. This 1 kilogram with which I'm comparing weights of different objects. This 1 kilogram with which I'm comparing the weights of different objects I will be calling it as I will be calling it as reference.

[00:21:01]I'll be calling it as reference or I can call it as standard.

[00:21:05]I can call it as standard. This 1 kg with which I'm comparing the weights of different objects. I'm calling this 1 kg as the reference or standard. Right?

[00:21:15]with which I'm comparing the weights of different objects.

[00:21:19]Now my dear students in chemistry we deal with atoms we deal with molecules right? In chemistry we deal with atoms we deal with molecules. Can I say in chemistry we should have a standard a reference like this 1 kg. In chemistry we should have a standard we should have a reference like this 1 kg with which I'll be comparing the weights of different atoms or molecules.

[00:21:48]So in chemistry we should have a standard in chemistry we should have a reference right with which we'll compare the weights of different atoms with which we'll compare the weights of different molecules.

[00:21:59]Yeah. So my dear students let's try to make that standard let's try to make that reference in chemistry with which we are going to compare the weights of with which we are going to compare the weights of different atoms or different molecules. Let's try to make that stand.

[00:22:16]How do you exactly make that standard?

[00:22:18]Let me show that to you. My dear students, in order to make the standard in chemistry, I will be taking a carbon 12 atom.

[00:22:28]I will be taking a carbon 12 atom. What am I going to do? I am going to make a standard in chemistry with which we are going to compare the weights of different atoms or molecules. And in order to make that standard, I'm taking the carbon tool atom. Let this be your carbon tool atom.

[00:22:46]Let this be your carbon 12 atom. Now my dear students, what exactly am I going to do is I am going to divide this carbon 12 atom into 12 equal parts.

[00:22:57]I divided this carbon 12 atom into 12 equal parts.

[00:23:01]Right? And my dear students after dividing the carbon 12 atom into 12 equal parts if I take the smaller part here can I say the mass of the smaller part the mass of the shaded part is nothing but it is 1 by 12th of the mass of it is 1x 12th of the mass of the carbon 2 atom.

[00:23:26]Yes, I can say that I took the carbon dual atom. I took the carbon to atom. I divided the carbon tool atom into 12 equal parts. I took one small part over here. Can I say the mass of this smaller part is nothing but 1x 12 of mass of carbon to atom. And my dear students 1x 12 of mass of carbon total atom. This is something I'll be calling as 1 amu from now onwards or you can call it as 1 U as well. You can call it as 1D as well. And let me tell you this amu is nothing but we call this as the atomic mass unit. And this U over here this is what I call as the unified mass.

[00:24:08]And this D over here this is what I call as Dton. This is what I call as Dton.

[00:24:14]Okay. So again what I'm trying to do is I have to make a standard in chemistry.

[00:24:20]I have to make a reference in chemistry with which with which I'll compare the masses of different atoms or molecules.

[00:24:27]In order to make that standard in order to make that reference I took the carbon tool atom I divided this carbon to atom into two equal parts. I took the smallest part and its mass is nothing but 1x 12 of mass of carbon to this 1x2 of mass of carbon to atom is what we call as 1 amu. It can be also called as 1 U. It can be also called as 1D. And this amu stands for atomic mass unit. U stands for unified mass. D stands for delton. Right?

[00:24:56]Now guys try to understand there was a technique used. There was a technique used called as mass spectrometry.

[00:25:09]There was a technique used called as mass spectrometry.

[00:25:13]With the help of mass spectrometry, with the help of mass spectrometry, the mass of entire carbon 12 atom was calculated and it was found out to be 1.99 into 10^ -23 g. First of all, by which technique?

[00:25:31]Mass spectrometry. With the help of mass spectrometry, the mass of entire carbon total atom was calculated. How much?

[00:25:38]1.99 into 10^ - 23 g. Yes. Now my dear students if we know see first of all this is the mass of entire carbon tool atom. This is the mass of entire carbon tool atom. If you got the mass of entire carbon total atom, if you got the mass of entire carbon tool atom, if I divide mass of entire carbon to atom with 12, that means if I divide this 1.99 into 10^ -23, if I divide this particular term with the number 12, I'll be getting the exact value as 1.66 into 10^ -4 g.

[00:26:18]Now, if I ask you what is this 1.66 66 into 10^ - 24 g. Is it the mass of entire carbon to atom? No. This is the mass of the shaded part. This is the mass of the smallest part over here.

[00:26:32]This is the mass of entire carbon to atom. This is the mass of entire carbon tool atom. And this is the mass of the small shaded part over here. And people at the same time remember one more thing. Remember one more thing. This 1.66 66 into 10^ - 24 g. It can be also written as 1 divided by Avagadro's number. 1 divided by Avagadro's number.

[00:26:54]I hope all of you know the value of Avagadro's number which is how much?

[00:26:58]6.022 into 10^ 23. So let me tell you if you divide one if you divide one with the Aadro's number the value comes out be same as of 1.66 into 10^ minus 24.

[00:27:12]Yes.

[00:27:14]Now people whatever things I told you till now whatever things I told you till now I'm going to summarize it in one statement I am going to summarize it in one statement my dear students I'm writing 1 amu and you know 1 amu is also called as 1 U 1 U is also called as 1D how did we define it we defined it as 1 by 12 of the mass of carbonar Right? Its value came out to be 1.66 into 10^ - 24 g. And in terms of Evagu's number, we wrote it as 1 / na g.

[00:27:57]Perfect. This is the summary of the things which I told you till now. This is the summary of the things which I told you till now.

[00:28:07]Summary of the things which I told you till now. Yeah.

[00:28:13]This is the summary of the things which I told you till now.

[00:28:17]Now guys, where do we use it?

[00:28:21]Where do we use it? Try to understand.

[00:28:24]For example, for example, I'm writing a statement here. The statement is pretty simple. I'm writing atomic mass of nitrogen.

[00:28:36]I wrote a simple statement. Atomic mass of nitrogen. If I ask you what does it mean? Atomic mass of nitrogen. What does it mean?

[00:28:44]What does it mean? It means that I'm talking about It means that I'm talking about the mass of It means that I'm talking about the mass of one atom of nitrogen.

[00:28:58]It means that I'm talking about the mass of one atom of nitrogen. I wrote a simple terminology over here. Atomic mass of nitrogen. What does it mean exactly? It means that I'm talking about the mass of one atom of nitrogen. And I believe every one of you would be already knowing what is the mass of one atom of nitrogen. It is nothing but 14 amu.

[00:29:17]It is nothing but 14 amu.

[00:29:20]It's nothing but 14 amu. And my dear students, can I write this 14 amu as 14 multiplied by 1 amu? I can do that.

[00:29:29]Right? Can I do one more thing? Instead of 1 amu, can I write 1x 12th of mass of carbon 12 atom? Absolutely I can do that. Instead of 1 amu, can I write 1.66 into 10^ - 24 g? Absolutely I can do that. Instead of the same 1 amu, can I write 1 divid's number? Absolutely I can do that. Right? Absolutely I can do that. Now think about it very clearly.

[00:29:56]What did I write? What did I write? I wrote the term atomic mass of nitrogen.

[00:30:01]That means I'm talking about the mass of one atom of nitrogen. And the mass of one atom of nitrogen is nothing but 14 amu.

[00:30:10]Okay, it means that one atom of nitrogen is 14 times heavier than 1 amu. It means that one atom of nitrogen is 14 times heavier than 112th of mass of carbon 12 atom.

[00:30:24]This is the mass of one nitrogen atom in grams. Even this is the mass of one nitrogen atom in grams. Even this is the mass of one nitrogen atom in amu.

[00:30:36]Did you understand?

[00:30:38]Did you understand people?

[00:30:42]Did you understand? This is the mass of one nitrogen atom in amu. This is the mass of one nitrogen atom in grams. Even this is the mass of one nitrogen atom in grams. Right?

[00:30:54]Yes, I believe this is clear guys in the batch lectures are very detailed. Don't worry very very very detailed again my dear students if I write one more statement for example I'm writing the term I'm writing the term atomic mass of oxygen I'm writing the term atomic mass of oxygen what does it mean it means that we are talking about the mass of one atom of oxygen it means that we are talking about the mass of one atom of oxygen how much is it how much is atomic mass of oxygen you must be knowing it's 16 amu can I break this 16 amu as 16 mult* 1 amu I can do that instead of 1 amu can I write 1x2 of mass of carbon to atom absolutely I can do that instead of 1 amu I can write 1.66 66 into 10 raised^ - 24 g absolutely can be written instead of 1 amu can we write 1 divid g absolutely can be done absolutely can be done so I wrote a statement here I wrote atomic mass of oxygen that means mass of one atom of oxygen how much is that 16 amu it means one atom of oxygen is 16 times heavier than 1 amu 16 times heavier than 11 12th of mass of carbon 12 atom right this is the mass of one oxygen atom in grams. Even this is the mass of one oxygen atom in grams. Even this is the mass of one oxygen atom in what? In amu. Right? So if I ask you one thing, what kind of information this atomic mass gives us?

[00:32:31]What kind of information this atomic mass gives us? See atomic mass of nitrogen is 14 amu. It means one atom of nitrogen is 14 times heavier than 1 amu.

[00:32:41]One atom of oxygen is 16 times heavier than 1 mu. One atom of sodium is 23 times heavier than 1 mu.

[00:32:48]Can I say can I say atomic mass?

[00:32:55]Can I say atomic mass gives an idea about?

[00:33:02]Atomic math gives an idea about how many times how many times an atom of an element an atom of an element is heavier than is heavier than 1 amu.

[00:33:30]Atomic mass gives an idea about how many times an atom of an element is heavier than 1 amu. Quickly tell me in the chats if this particular stuff is clear till here. Everyone in the chats people.

[00:33:45]Everyone in the chats.

[00:33:47]Yes.

[00:33:49]I think there are some glitz in the video because my internet is not stable today. There's something wrong with my internet.

[00:33:57]Yes. The badge price is going to increase tomorrow.

[00:34:01]So do get enrolled today only.

[00:34:12]Perfect. All right. Now guys, there's one more thing which I would want to discuss with you. What is that? See, for example, I'm taking an element nitrogen.

[00:34:20]I took the element nitrogen. Right. Now for example for nitrogen the first term which I'm writing that is 14 amu the second term which I'm writing for nitrogen just 14 just 14 no units the third term I'm writing 14 into 1 amu and instead of that 1 amu I'm writing 1.66 66 into 10^ - 24 g.

[00:34:45]Let me tell you the first terminology here which is 14 amu. This is something I'll be calling as the atomic mass of nitrogen.

[00:34:56]This particular term just 14 without the units. I call this term as the relative atomic mass of nitrogen.

[00:35:05]You call this as the relative atomic mass of nitrogen. And this particular term my dear students it is called as the actual mass of nitrogen.

[00:35:15]This what you call as the actual mass of nitrogen.

[00:35:19]Yeah. Similarly guys for example you have got the element sodium. Now tell me for sodium how many terminologies can I write? For sodium the first term I can write as 23 mu. The second term is just going to be 23. Third term is going to be 23 into 1.66 66 into 10^ - 24 g. Tell me one thing. What is this 23 amu? It is the atomic mass of sodium.

[00:35:46]What is this 23? We call this as the relative atomic mass of sodium. What is this particular term? I call this as the actual mass of sodium.

[00:35:56]Actual mass of sodium. I believe it's clear to everyone.

[00:36:01]I believe it's clear to everyone.

[00:36:04]Yeah. I believe it's clear to everyone.

[00:36:08]Perfect.

[00:36:11]Now my dear students, if I write a small question over here, I would want you guys to give it a try.

[00:36:20]Calculate the mass of 10 oxygen atoms.

[00:36:28]Calculate the mass of 10 oxygen atoms.

[00:36:31]Number one in amu.

[00:36:36]Number two in grams.

[00:36:42]Number three number three in kilogram.

[00:36:48]Calculate the mass of 10 oxygen atoms.

[00:36:52]Calculate the mass of 10 oxygen atoms in amu in gilg.

[00:36:59]Now my dear students, since we are supposed to calculate the mass of 10 oxygen atoms, right? We are supposed to calculate the mass of 10 oxygen atoms, right?

[00:37:13]We are supposed to calculate the mass of 10 oxygen atoms. Well, we do not know the mass of 10 oxygen atoms, but we know the mass of one oxygen atom. We know the mass of one atom of oxygen. And tell me in the chats, what is the mass of one atom of oxygen? at a 16 amu in terms of grams it's going to be how much it's going to be 16 into 1.66 66 into 10^ - 24 g, right? And if I divide the same term with 1,000, it comes in kg as well. It comes in kg as well.

[00:37:46]Yeah, it comes in kg as well. So basically the mass of one atom of oxygen in amu is this much in grams is this much. But am I supposed to calculate the mass of one atom of oxygen? No. I need to calculate the mass of 10 atoms of oxygen. This is the mass of one atom of oxygen. Right? If the mass of one atom of oxygen is this much, therefore the mass of two atoms of oxygen multiplied by two, three atoms multiplied by three, four atoms multip 10 atoms multiplied by 10. I would say the mass of 10 atoms of oxygen would be 116 into 10 comes out be 160 amu. Right? 16 into 10 comes out be 160 into 1.66 into 10^ -4 g. This is the answer of your first question. This is the answer of your second question.

[00:38:35]Right? And the answer of your third question will be simply divide this term with 1,000. You'll be getting the answer in kilograms. That's all.

[00:38:45]Yes.

[00:38:47]Am I clear people? Did you understand?

[00:38:49]This was a simple basic question.

[00:38:52]This was a simple basic question my dear student. Absolutely. You can write it as 160id na g as well. Yes, you can write it that way as well.

[00:39:02]Okay.

[00:39:05]My dear students, one more type of the question which I can give you over here.

[00:39:09]For example, the question is like this.

[00:39:14]If 1 amu is defined as If 1 amu is defined as 124th of the mass of carbon tote of the mass of carbon tote.

[00:39:34]Calculate the atomic mass.

[00:39:41]Calculate the atomic mass of oxygen as per the new scale.

[00:39:52]This can be one more question asked.

[00:39:56]This can be one more question asked. My dear students, now let's get to know how this sort of a question is tackled. Try to understand.

[00:40:03]First of all, what is the scale that we have chosen already? The scale is pretty simple that we have chosen already that is 1 amu is defined as 1 by 12 mass of carbon to this scale that we chose already as per the question what is the scale which is to be chosen as per the question the scale that is to be chosen is as per the question the question is saying the question is saying that define one amu as 1x 24th.

[00:40:39]The question is saying that define 1 amu as 1x 24th of the mass of carbon to see these are the two scales over here.

[00:40:49]This is the scale that we have chosen.

[00:40:51]This is the scale that is given to me as per the question. So this is my old scale basically this is my new scale as per the question and new scale let me not call this as amu let me call this is amu dash just to differentiate which is old scale and which is new scale.

[00:41:08]Now people what do we have to do? We have to calculate the atomic mass of oxygen as per the new scale. As per the new scale.

[00:41:18]Well we know the atomic mass of oxygen as per old scale.

[00:41:22]We already know the atomic mass of oxygen as per old scale. How much is that? That is 16 amu.

[00:41:30]But what do we need? We need the atomic mass of oxygen as per new scale. That means we don't need the answer in amu.

[00:41:38]We want the answer in amu dash. So what I'll be doing? Understand? Call this equation one. Call this equation two.

[00:41:45]Okay. The first step will be divide these two equations. When you divide these two equations, what do you get?

[00:41:51]You get 1 amu divided by 1 amu dash 1 am a mu divid by 1 amu dash this term this term cancels out in the numerator it's 1x 12 in the denominator it's 1x 24 the value comes out be two because 24 goes up 12 comes down it comes out be two so 1 amu divid 1 a mu dash is equal to so can I say 1 amu is equal 2 into 1 is 2 so 2 * amu dash 1 amu is nothing but it is 2 * amu dash Right? 1 AMU is nothing but 2 * amu dash. Since you got to know 1 amu is equal to 2 * amu dash. Now 16 into 1 amu. I can write it like this. 16 amu. I can write it as like this. Right? Now you know your 1 amu. Your 1 amu is nothing but it is 2 amu dash.

[00:42:42]The value comes out be 32 amu dash. What is this 32 amu dash? It is the atomic mass of oxygen as per the new scale which I was supposed to calculate. Did you understand?

[00:42:54]Did you understand people? Am I clear to everyone? Did you understand?

[00:43:00]Yes.

[00:43:14]Perfect.

[00:43:16]So I hope you clearly got the meaning of what atomic is and what kind of simple simple questions can be framed from this. Yeah, I'm giving you one question as a homework. Do give it a try and let me know its answer in the comment section of this particular video. The question is like this. If 1 amu is defined as 16th of the mass of carbon to life 16th of the mass of carbon to life.

[00:43:52]Calculate Calculate the atomic mass of nitrogen as per the new scale.

[00:44:10]Now this is the question which is your homework question people and you are going to let me know its answer in the comment section of this particular video. Someone is asking why carbon was taken as a reference. You'll get its answer on 20th of May in the first class. Okay.

[00:44:28]So just curious to know your height. I'm exactly 6 feet. Exactly six.

[00:44:37]All right.

[00:44:39]Hello guys. This was a very small session because a lot of students ask me how the class are going to happen. This is how your class are going to happen in the Phoenix 2.0 batch.

[00:44:48]Right.

[00:44:51]Perfect.

[00:44:56]All right guys, and those students who did not get enrolled yet, enroll quickly right after the session because right now the cost of the batch is some 469.

[00:45:04]Tomorrow it's going to hike up. It's going to increase. Okay. So do get enrolled as soon as possible right after this particular video.

[00:45:12]And if you have got any sort of doubts related to the batch, you can let me know in the comment section of this particular video. Okay.

[00:45:19]Sh. With this I'll be taking a leave today. I'll see you in my next session.

[00:45:23]I'll keep on coming up with these small small sessions till 20th of May so that you remain in touch with your books.

[00:45:29]Yeah. Then from 20th of May we are starting directly our batch without any sort of delay.

[00:45:36]All right. That when will batch start in the app? Batch starts in the app on 20th of May.

[00:45:46]Ch guys. See you. Take it.
