Molar Mass (Revised)

Front

What is molar mass?

Back

Molar mass is the mass of one mole of a substance, typically expressed in grams per mole (g/mol). It is calculated by summing the atomic masses of all atoms in a molecule.

How do you calculate the molar mass of a compound?

Back

To calculate the molar mass, identify the number of each type of atom in the compound, multiply by the atomic mass of each element, and sum the total.
