Answer:

The mass of one mole of the substance.

Explanation:

In chemistry, the molar mass is a physical property defined as the mass of a given substance divided by the amount of substance. The base SI unit for molar mass is kg/mol. The most practical chemical molar mass used is g/mol because kilogram quantities are not usually used in chemical experiments.
