What is the concept of normality and formality?how it will calculate?

1. Molarity. The molarity of a solution is the number of moles of the solute contained in one liter of the solution.

Molarity = (number of moles of solute )/Liter of solution

2. Formality. The formality of a solution is the number of gram-formula weights of the solute contained in one liter of the solution.

Formality = (number of gram of solute/gram-formula weights of the solute)/Liter of solution

3. Normality. The normality of a solution is the number of gram-equivalent weights of the solute contained in one liter of the solution.

Normality = (equivalents of X)/Liter of solution
