The number will of course depend both on the formula of the substance and on the weight of the sample. But if we consider a weight of substance that is the same as its formula (molecular) weight expressed in grams, we have only one number to know: Avogadro's number, 6.022137 × 1023, usually designated by NA.

Some Notes on Avogadro's Number, 6.022 x 1023 ... Chemists use Avogadro's number every day. It is a very valuable number for a chemist to know how to use, and use properly. Where did Avogadro's number come from? Did Avogadro himself do all the calculations? Was it just arbitrarily made up?

Experiments based on this principle eventually led to the calculation of the number of molecules in one cubic centimeter of gas. This number of molecules was determined to be roughly 6.02 x 1023; this was dubbed "Avogadro's number."
