Atomic mass is the mass of an atom and is given in a.m.u. (atomic mass unit).
However, a molar mass is the mass of one mole atoms or molecules and is given in grams.
one mole is equal to Avogadro's number ( Na = 6.022 * 10^23 )atoms or molecules.
For example:
Sodium atom has a mass of 23 a.m.u. however, the molar mass of sodium is 23g/mol.
