The normality of a solution is the gram equivalent weight of a solute per liter of solution. Here are examples of the normality formula.
Normality is a measure of the number of grams equivalent to solute present given volume of the solution. Redox reactions, precipitation reactions, and acid-base chemical reactions all often make use of normality.

How to Calculate Normality of a Solution - Science Notes and Projects
Normality expresses concentration in terms of the equivalents of one chemical species that react stoichiometrically with another chemical species. Note that this definition makes an equivalent, and thus normality, a function of the chemical reaction.
Normality is defined as the number of gram or mole equivalents of solute present in one liter of solution. The SI unit of normality is equivalents per liter (Eq/L).
The beauty of normality is that identical volumes of any acid solution will exactly neutralize the same volume of any base solution, regardless of the acids or bases involved if their normalities are equivalent.
Normality is commonly used in acid-base chemical reactions, redox reactions, and precipitation reactions. It depends on the chemical process under observation and the temperature.
Normality expresses the concentration of a solution based on the number of gram equivalents of solute per litre of solution; this makes it especially useful for reactions where just the mole concept is not sufficient, such as acid-base or redox reactions involving varying reactivity.
