- This lecture is about atomic mass unit in chemistry. In this animated lecture, I will explain you the easy concept of 1 amu and how many grams are there in 1 atomic mass unit.
Q: What is atomic mass unit?
Ans: Atomic mass is defined as the unit used to measure the mass of atoms which is equal to one twelfth of the mass of an atom of carbon 12 is called atomic mass unit or 1 amu.
To learn more about atomic mass unit and its derivation, watch this lecture till the end.

You cant maiured how much I love your videos
😅
😂😂
to be honest, I like your teaching more than any other UA-camr thanks, and also plz make class 11 more videos about new syllabus
totally agree😊
Chup
Dudeeee no one can explain amu better then this... I'm rooting for your growth!!!!
Exactly , First I thought chemistry is a boring subject🤔🤨 but since I joined this channel my concepts have become crystal clear 👌👍
May Allah grant this teacher long and peaceful life ...
,,🤲🤲🤲
Many many congratulations🎉🎉 to sir.❤😊
thank you sir! You people solved my problem❤❤
Sir i love your video so much that i cannot meiyer it aalso i like your video thousand times
Wow u explain in a very easy method
Sir your explanation is crystal clear I am very very proud of you. and my confusion is very far away from me , Thanks a lot sir thanks a lot..... Sir please make video continuosly for class 11 .we all support you and you also support us
🎉🎉🎉 congratulations 🎉🎉🎉
You cleared your base of chemistry❤❤❤❤❤❤❤❤❤❤❤❤❤❤
I’m in 6th in this hope so many problems I had, this video helped me a lot,Thank you.
Waah waah waah kya baat hai sir ye sab kaise kiya aapne ji mujhe 12 salo me samjha nhi paya oo aaj samjh gaya thank u so much and love u sir
Hat's off to your teachings Sir 👏👏👏
😭😭tq so much... You understood the students feelings well....
Kindly make a detail video in simple that how a cell works that we use in our home gadgets.
Actually it's very confusing.
I will be very thankful
I will...
Thanks
Thank you Sir concept is now crystal clear
Had a great misconceptuality in this topic. Now crystal clear Thankyou very much ❤️❤️!!
😮damnnnn , the way you've explained it 😊
Your the best teacher
I am thinking that if you become my chemistry teacher
Thank you SO much😁❤️ I was struggling to rap my head around atomic mass unit for so long and this answered all of my questions 🌟
Sir, you are very underated
You have cleared all my doubts
Thank You sir❤❤❤
Thank u so sir i watch more videos of you and get more information ❤
Really, you are the best. Your explanation is very helpful.
Thankyou Sir for your wonderful tricks and your teaching is marvellous sir
Sir i am in class 9 there are so many difficuties to me now i understand the whole topic very smoothly i also appreciate you
Thankyou so much for best explanation
Really good concept for any student
Good job
#First
sir love your videos 😍😍
Thank you!!!
🙏🙏🙌🙌
@@NAJAMACADEMY Love you sir your videos are awesome and super helpful for my jee preparation and also for all the students.
You are amazing sir. Thanks a lot ♥

You are out standing teacher
Your video is excellent💯👍👏
Thank you so so so much sir 🙏🙏❤️❤️🙏🙏
Amazing work 😉
Honourable sir can you reveal your face 😅
S .. very super explanation..
He is cartoon
fantastic way of teaching😗
I waste my time on unacademy magnet brains physics wallah but all are only waste but u are great ❤
@@kawai4469 are u in class 9
Yes u are right 👍 I also
I don't think they are waste 😂
Only because of PW I am in mbbs right now
Rest ofc whatever works out for you is the best 🫰🏻
🙏🙏🙏🙏I have no words for you 🥺🥺
to be honest ,i finally get the meaning of the atomic mass unit ,thank u very much sir
Thanks you do much ❤your lectures are very outstanding❤ Thanks✨
thank you big brother you have helped me so much God bless you so much.
Am called Agah de man256 from kyenjojo Uganda.💖🥳
Good
❤❤ Thank you very much sir
As we know that we can't take one atom of any atom r can't touch or see so how we cut
carbon atom in 12 peices and how to compare with other atoms?
We are just dividing the total mass of carbon atom in 12 parts for reference so that we can compare the mass of other atoms with respect to it and not actually cutting it with knife😜
@@RadheKrishna-yu6sj hello my friend ... can u solve my doubt??
1 Amu = 1/12th mass of one carbon atom = 1.66*10^-24 gram
Mass of one proton/neutron = 1.66*10^-24 gram ..
Why can't we just simply say 1 amu = mass of one proton/neutron...
@@nishchalsucksatjee7404 we can say
Thank you very much
Sir, your way of teaching is best❤❤❤❤❤❤❤❤❤ 8:39 8:40
Very nice and crytal clear explanation, well done.
Great cls sir ... Thank you sooo much 🌈✨. Love from kerala 🤠
Thanku sir for this class
Really super thank u so much
How can one explained this much good🎉
Give me one heart ❤️
Thank you so much for your love and support!!!
🙏🙏
Love you sir from Pakistan 🇵🇰🇵🇰
Amazing,Thank GOD
I found your video ,before listening your lecture about this topic.I was much confused
I used to try to found related to amu derivation means how the value of 1 amu is developed but no one video have information about its derivation
now , I have not a words to explain that how amazing this video's explanation is this❤❤❤
thank you so much sir ☺️☺️💕.
Thank you sir
Thanks so much sir.....
Very very nice explanation 🤩🤩
Fantastic explanation no words
Amazing
There is noone who can expalin better than you sir❤️
Extraordinary
amazing, thank you for the explanation
Great , excellent and good lecture sir ❤❤❤😊😊
Wish to thank you sincerely for this lesson
Welcome
🙌🙌
Thank u sir 🙏☺️
Dude i have done msc chemistry but watching ur videos to clear my concepts😂❤
Sir How do we know that 16 amu is equal to mass of 1 oxygen atom?
Thank You Sir, Namaste

Thank you bro
Nice information tq
What does he mean when he says , "Mayyered?".
Measured😂 i
Measured ...
Thanks, good explanation
Thank u sir❤
hello my friend ... can u solve my doubt??
1 Amu = 1/12th mass of one carbon atom = 1.66*10^-24 gram
Mass of one proton/neutron = 1.66*10^-24 gram ..
Why can't we just simply say 1 amu = mass of one proton/neutron...
Also i have a doubt.. Instead of multypling like this we can just find out the mass of one atom no. Of protons * massof one proton + no. Of one neutron * no of neutrons?
Must say you provide simple analogies
Best explaination
asalamu caleykum bro can you tell me the difference between when we say comes from Latin word and Greek word
May Allah swt bless you
So nice ❤👍
Amu is always expressed in fraction number not a whole number I guess
You are the best 👋
I really appreciate your way of teaching,thanks alot
Thank you so much😅the confusion..has been vanquised now
Amazing sir... I could understand this concept clearly and thank you so much sir...👍
Very very nice teaching
I am from Dubai 🇦🇪
Sir can u answer me plz
On one side u r saying that mass in gram of carbon is 12 and on the other hand u r multiplying the value of 1 amu with it so what's the difference plz make me crystal clear
👏👏👏
9:06 sir here you did a mistake
Thx
Many FSC complete ki hoi hy, 4 saal chemistry👨🔬 ma passing marks ly kr paas hova 0% samaj aati hy, yeh video dekh kr 3% samaj aa gai 🤝❣️🤗😁
In RAM why we take carbon as standard measurements?
It is due to following reasons:
1) Its abundance
2) Its reactivity
3) Its stability
4) Its uniqueness
😊😊
Thank you sir i now kew relative atomic mass
🥰🥰🥰
And the reason why the mass of a proton is not exactly 1 amu is because the protons and neutrons that makeup a C-12 atom (and all atoms) are known to weigh different amounts? Therefore, the mass of one proton and one neutron is not exactly equal to 1 amu? My Chemistry book says that 1 proton weighs 1.0073 amu and one neutron weighs 1.0087 amu. How is that possible since that adds to more than 12 amu for a C-12 atom?
before this video i was very confused but now i have understood well!!❤❤
Bro killed it 🤙🏻
Please discuss trick for mcqs
Very beautifully explained. Thankyou 🙏🏻
1 amu = 1 over 12 of carbon-12, not any carbon atom since carbon has two stable isotopes, carbon 12 and carbon 13.
it is carbon 12 since it is an atom that has relative atomic mass of 12.0
it could be any atom, but carbon 12 was chosen since it has 6 protons, 6 neutrons and 6 electrons.
Great video man
Isn’t the avogadro number 6.022 x 10 raised to 23?
You are right ,it is😊
Thank you very much sir 🙏
