Atoms and Molecules Moles - The Chemistry Guru

So, the number of atoms in 1 gram-atomic mass of element and that of molecules in 1 gram-molecular mass of a substance must be the same as the atoms in exactly 12 g of 12 C. An assemblage of this number (N) of particles is known as a mole (mol when used as a unit), which may be defined as follows.
