Front

Define molar mass.

Back

The mass of one mole of a substance, typically expressed in grams per mole (g/mol).

Front

What is Avogadro's number?

Back

6.022 x 10²³, the number of atoms, molecules, or particles in one mole of a substance.

Front

How do you convert grams to moles?

Back

Divide the mass of the substance (in grams) by its molar mass (in g/mol).

Front

How do you convert moles to grams?

Back

Multiply the number of moles by the molar mass (in g/mol).
