Question

how can we calculate number of atoms in a compound​

Answer 1

Yes , we can calculate

Just multiply the molar amount means the number of moles present in the atom with the avogadro's number which 6.022×10^23.You will get the number of atoms.

Hope u understood.

Answer 2

First we have to know the molecular weight or basically the weight of the compounds.

Generally there are Avagadro (6.022×10^22)no.of molecules in the compound.

Then we have to compare the no.of molecules in the give weight of compound.

Hope it helps;-)
