From more than 3 days I search this concept on RUclips but not even a single video had cleared me out and now I finally got this concept in this video
This is the most underrated youtube channel I swear
Bhai ye emoji kese bheja
😅
Finally got the concept

bestest sir u r great just loved how easy u make it easy for us thank youuu so much sir
2024 ........... students 🤌🏻✨
I am medical student and neet aspirants i am preparing for neet in allen career institute but still watching sir
What is meant by this?
Relative atomic mass = Mass of one atom of an element/ 1/12th part of the mass of one atom of c-12
Ek carbon -12 lo which is an isotope of carbon. Agar is carbon ko 12 equal hisso mein baat de toh jitna weight ek hisse ka hoga wo hoga 1/12th the mass of carbon atom
Hi
Thakns a lot sir ..i think its difficult to understand but if u teaching then it impossible.thanks a lot 🤩

Sir all that clear but I can't understand that how to known that the mass number of carbon had been 12 before the explanation of this topic, relative atomic mass 🤔🤔🤔
BY THE WAY YOUR EXPLANATION IS VERY VERY VERY PERFECT ❤❤❤❤
App sach me bhut briya prate hai... thanku sir ji..
We are glad to know that you found our app useful. Keep using it and let us know if you need any help.
Thank you sir
You are best sir 😊
Good video ! Which instrument/technique can we use to calculate the mass of the 1/12th carbon atom?? and if we compare the actual mass of the hydrogen atom to the actual mass of the carbon-12 then what would be the difference ?
Hii
Finally i got it. Sir. ♥
Thank you so much Dear sir🙏 you are really help us in our study 😊
Thank you for taking the time to watch our educational videos! We're glad that you found them helpful in your studies. Keep up the good work and we hope that our videos will continue to be a valuable resource for you.

Bro which book do you prefer for physics and chemistry.plz tell I don't know which book do I use so.😢😢😢😢
@@user-ni8pm2fh1d i mainly using ncert of chemistry, physics but i also have allen module which they gave me for neet preparation
What was ur score in 11th

Hello sir
Hi
Sir laws har jagha alag alag mil rhe h
Idhar kuch aur meaning nikalta h
Udhar kuch aur
TQ so much sir...ur vedios are very helpful for me ☺️

Finally I understood the concept thankyou so much sir 🥰🥰🥰🥰
Sir thank you soooooo much sir I am Pakistani but Pakistan ma app ke Tara koye be nahe ha I am Pakistani but I proud you
Apka video exilent h sir I Understand all topics
Sir Avogadro law lecture ?
Thanks for your comment! We are currently working on the lecture series and it will be available soon. Keep a lookout for the new updates!
Respect for magnet brains 🗿
thank you sir ji❤❤
Sir i have no words for your so much easy explanation i loved it
Hope you will always teach like this in very deep and easy way ❤❤❤🎉🎉
And thanks to Magnet brains effort ❤️❤️❤️
Sir atom ko to humlog further tor ni skte hn n phir C12 atom ko 12 parts me kaise divide krenge
Sir mein aapne man se liya hai reactants ko 2H2 +o2 ------- 2H2o
Then solve, (2vol.) (1vol.) (2vol.)
So, ratio is = [2:1:2] Ans.
Finally i got the best teacher for chemistry ❤
Sabse best sir🎉
Easy explanation for me😊😊😊

Yani k, atomic masses for all the elements were found BECAUSE of Relative Atomic Mass???? Agar aisa hai tou, AA-LA, KHOOBSURAT !!
Sir hamare book me Atomic mass or Moleculer mass dono alag alag hai
Also start bio
Thanks for your suggestion! We are always looking to make our videos more relevant and helpful for our students. We appreciate your feedback and will consider it in our next video. Thanks for watching!
Sir app na Kamal kar dia
Sir 1amu=1.66×10-24g is that's right or wrong
Yes, you are absolutely right! 1 amu equals 1.66 x 10^-24 grams.
Mass lecture 🎉🎉🎉
Thank you so much for enjoying our educational videos! We're so happy to hear that you're finding them helpful and engaging. We hope you continue to enjoy our videos and learn a lot from them!
