Molar mass is expressed in

Explanation:
Molar mass tells you how much mass corresponds to one mole of a substance, so it is expressed in grams per mole (g/mol). This unit lets you convert between mass and amount: mass in grams equals moles times molar mass (g/mol). Grams per liter describes concentration, not molar mass. Moles per gram would be the reciprocal of molar mass, which isn’t the standard way to express it. Atoms per mole isn’t a unit used for molar mass. For example, the molar mass of water is about 18.015 g/mol, meaning one mole of water has a mass of 18.015 grams.
