Molecular mass is the sum of atomic masses in the molecule. Molar mass is the mass of one mole of the molecule. This turns out to be numerically the same as the molecular mass but the units are grams/mole!Relative molecular mass is the sum of the atomic masses of the atoms in the molecule. Relative formula mass is the sum of the atomic masses of the atoms in the empirical formula(Atomic subscripts reduced to their lowest terms). ... Formular mass applies to ionic compounds.

There is a cyclopean difference between molecular mass and formula mass.
Molecular mass is the mass of a given molecule or compound but now the clinch here is that it remains neutral despite the presence of zillions of molecules. For ex: Molecular mass of CO2 = 12*1 + 16*2=44.
2.But, now the formula mass is something different. IT IS THE MOLECULAR MASS OF THE WHOLE COMPOUND CONTAINING X NO. OF MOLECULES OF THAT COMPOUND. Let me clarify it with example: Like we have to find the formula mass of 10Na2SO4.H2O= 10[23*2+32+16*4+2*1+16*1] = 10*180= 1800.
