Sir,
H4 molecule ke 2 mole hai to H atom ke 2x4=8 moles honge.
Aapne 4 moles of H likha hai and 8 moles of H hai to total number of H atoms are 8 x 6.023 x 10^23
and that's why total mass of 8 moles of H atoms will be 8 x 6.023 x 10^23 amu.
ek hydrogen atom ka atomic mass 1 hota hai
Yes I was thinking the same there are 2 moles
One atomic mass value of hydrogen one hi hoti hai.. if the value would be H2 then 2 moles value hoti.. but yaha pr H4 Hai.. it means = 1×4 = 4
haan bro mai bhi yehi sochra tha 🌹

I m in 10th and i didnt remeber much about that 1/4π Epsilon not ×ze×e/r² ...... , It was very tough for me so i left most of the part .......
Also 1st time when i went in my coaching (vmc) in 8th class , i was so damn confused that what was sir teaching , that was far away from my syllabus and i learned that in 10th .......... , It was ion electron method of solving redox reaction , yeah i learned in 10th 😬 .
I have also studied pH calculation , basics of log concept which is necessary for finding pH and few small small concepts of 11th , idk why but i only like chemistry out of the 3

Ha brother Arjuna jee batch sey hu
Molar Mass:
First, we need to know the molar mass of methane (CH4). Each element in the molecule contributes its atomic mass to the overall molar mass.
Carbon (C) has an atomic mass of approximately 12 g/mol.
Hydrogen (H) has an atomic mass of approximately 1 g/mol.
In CH4, there's one carbon atom and four hydrogen atoms.
Therefore, the molar mass of CH4 = (12 g/mol for C) + (4 g/mol for 4H) = 16 g/mol.
Number of Moles of CH4:
We have 32 grams of CH4.
Using the molar mass we just calculated (16 g/mol), we can find the number of moles of CH4 present:
Moles of CH4 = Mass of CH4 / Molar mass of CH4
Moles of CH4 = 32 g / 16 g/mol = 2 moles
Mass of Hydrogen in CH4:
Each molecule of CH4 contains 4 hydrogen atoms.
Since we have 2 moles of CH4, the total number of hydrogen atoms:
Total H atoms = Moles of CH4 * Number of H atoms per molecule
Total H atoms = 2 moles * 4 atoms/molecule = 8 atoms
Mass of H atoms:
To find the total mass of hydrogen atoms, we need to multiply the number of hydrogen atoms by the atomic mass of hydrogen:
Mass of H atoms = Total H atoms * Atomic mass of H
Mass of H atoms = 8 atoms * 1 g/mol = 8 grams
Therefore, there are 8 grams of hydrogen atoms present in 32 grams of methane (CH4).
If anyone gets good marks in physics or chemistry credit goes to alakh sir ..

18-19 batch student here.. you really helped me to score good in physics in my 10th ICSE BOARDS!! THANK YOU SO MUCH SIR!!
A great thanks to Physics Wallah for this video. I had lots of confusion in this topic. But it's clear now👍
Sir, I think you should start private classes because you teach everything very nicely and India needs teachers like you. I am in 12 th and I got 96 in chemistry just because of you.
Priyansh Patel osm marks
Oh
Priyansh if he could teach privately..he could ..but his aim is to teach all the students. He want to help students like us.without expecting money or whatever
Congrats for 96 marks bro
@@suhanikumari6518 lol Your Exams Are Near Too Mine Also They Are 9 days away Lets Complete The Syllabus As Fast As we Can Oh i got Distracted ! shit ...
This lecture is really phenomenal, like a hour ago I wasnt getting the concept of moles and after this lecture I got it sooo well
I'm in grade 9
im from Pakistan, wanna say that Indian teacher teach really very well ngl 👉🏻👈🏻👌🏻💫❤

What topics are included in your 9th grade chemistry?
Let's match the indian curriculm with the pakistani 😅curriculm
I heard that you'll have matrices in mathematics in 9th grade?
Kon kon abhi dekh raha hai😅
5 years old video but the comment section is still active this is the power of our alakh sir..❤️🔥🔥

Zindagi me pehli baar samjh me aaya mujhe mole concept. Thank you so much sir 🙏🏼😌

Even after 7 years it also help the students❤ thank u sir🙏
Thank you sir for this wonderful explanation, now I am damn sure to tackle any question based on mole concept and this is only because of you sir.

THIS MAN REALLY GOT SOME TALENT
I'm a candidate of grade 9th . I watch his videos to find various numericals with sol.( to examine myself).. Being a JEE ASPIRANT ,I watch the topics of 11th . After watching these videos , I would like to say , " Some teachers must follow him to be an ideal teacher. From academical and ethical aspects, He is one of the best instances." Keep watching these engrossing classes.
Hey bro wanna contact u i am dropper preparing for neet
Broo Mene bhi 9th me hi ye padha tha now i'm in 10th Nd Esme chemistry me kuch khaas nhi Thaa sb complete kr liaa Ab 11th ka basic strong kar rhe hain (Maja ata hai cheme. padhne me)
TRUE WORTH WATCHING THESE 40 MINS....AWESOME TEACHING!!
कभी क्लास में ठीक से ध्यान दो
तो समझ आ जायेगा

Sir in 24:51 can't we do like this...
In CH4 we have 4 moles of hydrogen
So by formula no.of moles=mass given / molar mass
So in CH4 the given mass is 32 grams
4 moles = 32 g / X
X= 32/4 = 8
Sorry if I did wrong....btw I love Ur teaching sir 🙏
u r right
U r ri8... 8g of hydrogen hoga woh....
I think aise karna sahi nahi hai kyuki 32g me 1 mole C aur 4 moles of H atoms ...so aisa nhi likh sakte ki....
no of moles = given mass / molar masss
Kyuki given mass total CH4 ka h na ki only H4 ka !!
I hope it helps !!!
No we can't do that because in the question it's telling to find mass of hydrogen only, while mass of the whole ch4 is 32 g.
Ur right
Wow what a explanation No words to say about this fantastic lecture Thanks Sir
yes can't explain in words
Great sir. I clearly understood the basics of mole concept in class ten. Helped me wide in the boards

hats off to this person I was struggling with this concept for months this guy just cleared all of them in just 1/2 hour. we have legends on youtube so why do we even need to purchase the batches?
2 teachers I love most:
1. Anand kumar
2. Alakh pandey
U don't know reality of anand kumar
@@najmussehar11 u all think anand kumar to be great, me too but reality Is something else, I found out the truth
Harsh anand tell the truth then
Guys!!! Note:the question of calculate mass of hydrogen atom present in 32 g of methane ?? question sir said answer has 4moles but the right answer is 8 moles becoz 2 moles of methane give 2*4=8moles

To solve this problem, we'll use stoichiometry to find the mass of H2 required and NH3 produced.
1. Calculate the molar mass of N2:
Molar mass of N2 = 14 g/mol
2. Use the stoichiometry of the reaction to find the molar ratio between N2 and H2:
1 mol N2 : 3 mol H2
3. Calculate the number of moles of N2:
Moles of N2 = Mass of N2 / Molar mass of N2
= 14 g / 28 g/mol
= 0.5 mol
4. Use the stoichiometry to find the moles of H2 required:
Moles of H2 = Moles of N2 × (3 mol H2 / 1 mol N2)
= 0.5 mol × 3
= 1.5 mol
5. Calculate the mass of H2 required:
Mass of H2 = Moles of H2 × Molar mass of H2
= 1.5 mol × 2 g/mol
= 3 g
6. Now, use the stoichiometry to find the moles of NH3 produced:
Moles of NH3 = Moles of N2 × (2 mol NH3 / 1 mol N2)
= 0.5 mol × 2
= 1 mol
7. Calculate the mass of NH3 produced:
Mass of NH3 = Moles of NH3 × Molar mass of NH3
= 1 mol × 17 g/mol
= 17 g
So, the mass of H2 required is 3 grams, and the mass of NH3 produced is 17 grams from 14 grams of N2 gas.

It's 2023 October almost 6 years old, watching this module of Alakh Sir, it's really treasury for students... I didn't understand mole concept but Alakh Sir explained it very welll... Hats Off to Sir!! ❤
Watching this vedio after boards 😂😂😂and have no idea about mole concept because 9th maze me kri thi😂😂😂
Same here😊😊😊
