Question

differentiate between molecular and molar mass

Answer 1

My chemistry teacher told me that there is no difference between these two.

But according to what I have seen, molecular mass is the mass of 1 molecule.
Molar mass is the mass of 1 mole of a substance.
Remember, molecule is not always equal to mole.

Answer 2

moleculer mass is one molecule mass
molar mass is mass of complete compound
