Normality, Molarity, and Molality are different ways to express the concentration of a solution.

• Normality is the number of equivalents of a solute in a liter of solution.

• Molarity is the number of moles of solute in a liter of solution.

• Molality is the number of moles of solute per kilogram of solvent.
