mass= 64g
Molecular Mass of SO2= 32+16x2=64u
We know no. of moles = m/M
=64/64= 1 mole
Now, no. of moles = no. of atoms/Avogadro no.
1= no. of atoms/6.022x10²³.
no. of atoms= 6.022x10²³
Just remember this formula,
n=m/M=N/6.022x10²³
where n is no. of moles,
m is mass of substance,
M is molecular mass,
N is no. of atoms or molecules.
