This lesson covers solved numerical problems on molarity, molality, mole fraction, and percentage concentrations to help you clearly understand solution concentration concepts in chemistry.

Both molarity and molality are measures of a chemical solution’s concentration. The primary difference between the two comes down to mass versus volume. Molarity (M) is the amount of a substance in a ...
