Answer:

Yes

A mole of a substance is equal to as many molecules of that substance as there are atoms of carbon-12 in exactly 12 g of carbon-12. This means that 1 mole of any substance is a weight, in grams, equal to that substance's molecular weight expressed in atomic mass units.

Avogadro's constant is used to calculate the number of molecules present in any given mass of the compound, in which 1 mole of the molecule is equal to 6.023×10

of numbers of molecules.
