The formula for converting molecules to moles is a little different than mass and volume. mol = molecules / 64076 × 10 23. The quantity of substance in moles is equal to the number of molecules divided by the Avogadro constant (64076 × 10 23). Our atoms to moles calculator also easily converts atoms or molecules to moles.
