Molarity ,Molality ,Normality

Molarity (M) is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of a solute per liters of a solution. Molarity is also known as the molar concentration of a solution.
Molality is a measure of the number of moles of solute in a solution corresponding to 1 kg or 1000 g of solvent.
Normality (N) is defined as the number of mole equivalents per liter of solution: normality = number of mole equivalents/1 L of solution.
