Molecular mass: is the mass of the molecule relative to the 1/12 of the mass of C-12 atom. (Used to be relative to the mass of proton (or was it hydrogen atom?), I think, which is almost 1% heavier. )
Molar mass: of something (it must be composed of identical constituent particles, usually molecules) is the mass of as many particles as there are in 12 grams of C-12. This number is called Avogadro constant and is a bit over 6 x 10^23. This amount of something is called mole and is one of fundamental units in SI standar

Molar mass = mass of a mole of molecules, it is in atomic mass units
Molecular mass= mass of one molecule, it is in grams per mole units.
Molecular mass= mass of one molecule, it is in grams per mole units.
