The formula mass (formula weight) of a molecule is the sum of the atomicweights of the atoms in its empiricalformula. The molecular mass(molecular weight) of a molecule is its average mass as calculated by adding together the atomic weights of the atoms in the molecular formula.

Molecular mass is used for molecule i.e. covalently-bonded multi atomic substances.
Formula unit mass are used to describe ionic compounds . i .e. ionically bonded compounds found as lattice structures.
