What is molarity?

Back

Molarity is a measure of concentration defined as the number of moles of solute per liter of solution (mol/L).

Front

What is the unit of molarity?

Back

The unit of molarity is moles per liter (mol/L).

Front

How do you calculate molarity?

Back

Molarity (M) = moles of solute / liters of solution.
