The molarity of a solution is defined as the number of mole of solute dissolved in one liter of the solution. The formula for molarity is given by the expression shown below.

$\text{M}=\frac{\text{n}}{\text{V}}$

The relation between number of moles and mass of a substance is given by the expression shown below.

$\text{n}=\frac{\text{m}}{\text{Molar}\text{mass}}$
