Front

Define molar mass.

Back

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

Front

What is the formula to calculate the number of moles from mass?

Back

Number of moles = mass (g) / molar mass (g/mol).

Front

How many moles are in 36 grams of water (H2O)?

Back
