Gram Molecular mass gives the mass of a single molecule (sum of the atomic masses in the molecule), whereas molar mass gives the average mass of the molecule (mass of Avogadro number of molecules).

The difference between molar mass and gram molecular mass is that the molar mass gives the average mass of the molecule whereas the molecular mass gives the mass of a single molecule.

The main difference between molar mass and gram molecular weight is that molar mass gives the mass of a mole of a particular substance whereas molecular weight is the mass of a molecule of a particular substance.

EXAMPLE:-

Copper...

atomic mass = 63.55 AMU / atom

molar mass = 63.55g / mole.... mole of atoms that is.. 63.55g / 6.022x10^23 atoms

nitrogen...

atomic mass = 14.01 AMU / atom

molar mass = 14.01g / mole... mole of atoms again.. 14.01g/6.022x10^23 atoms

methane... CH4

MOLECULAR mass = 1x12.01 + 4x1.008 = 16.04 AMU / molecule

molar mass = 16.04g / mole.... mole of MOLECULES... 16.04g / 6.022x10^23 molecules .
