Ans: no. of molecules of ammonia = 0.75*6.02*10^23 no of atoms of hydrogen = 3*0.75*6.02*10^23 =1.35*10^24 is it correct? hello sir,
i have a simple chemistry question which i have solved but i am not quite sure of the answer:

Q: how many atoms of hydrogen are there in 0.75 moles of ammonia?
Ans:
no. of molecules of ammonia = 0.75*6.02*10^23
no of atoms of hydrogen = 3*0.75*6.02*10^23
=1.35*10^24

is it correct?
