as we know, No. oo Moles = given mass / molar mass so no of moles is 0.2 no. of molecules will be = 0.2*6.022*10^23 answer for no of molecules : 1.2044*10^23 as we know two oxygen atoms there are so multiplying no of moles *2 0.2*2=0.4 no of atom = 0.4*6.022*10^23 that is 2.4088*10^23 sir aap ne bht accha samjhaya jo concept mein class 9 ke end take nhi samjh paya aaj minton mein samjh gya.

OMG! Thank you so so so much sir! This explanation was the best. I saw so many other explanations, but just couldn't understand this concept. But now it so clear.👌🙏🙏
Sir you told about the magic in mole concept and when i understood the magic i realised you are a magician of one kind. Thanku sir. Pls keep your style.
Sir the way you explain is very clear. As sometimes during class we cannot understand and we think that we will ask afterwards that doubt . But, we won't and because of that small doubt we don't understand whole concept. U explain even those small doubts too. Which helps us a lot. U r the best teacher .☺
I think you are failure in your class because students who have to study asks the doubts And I also ask my every doubt But sanjiv sir is best so I see the videos of sanjiv sir
Sir, I've got 50/50 in my science test , credit goes to u🙃, sir ur best teacher and Ur teaching style is amazing, 💕 keep supporting in our studies by making our study easier 🤗
Sir last question answer : no of moles = 8.8 / 440 = 0.2 moles no of molecules = 0.2 x 6.022 x 10^23 = 1.2044 x 10 ^23 no of oxygen atoms present = no of molecules (1.0244) x 2 (no of oxygen atoms) = 2.0488 oxygen atoms

3) 3.011*10²²
thoda zaada nahi hogaya???
as we know,
No. oo Moles = given mass / molar mass
so no of moles is 0.2
no. of molecules will be = 0.2*6.022*10^23
answer for no of molecules : 1.2044*10^23
as we know two oxygen atoms there are so multiplying no of moles *2
0.2*2=0.4
no of atom = 0.4*6.022*10^23
that is 2.4088*10^23
