# Molarity Formula

Concentrations of solutions in chemistry are usually expressed as molarity. This is the number of moles of solute per liter of solution. To be able to find the molarity of a solution you need to know the mass of dissolved solute, the volume of the solution and the molar mass of the solute.

"Molarity is defined as the number of moles of solute dissolved in 1 liter of solution."

Molarity Formula is given below.

$Molarity=\frac{number\quad of\quad moles\quad of\quad solute}{L\quad solution}$

Thus, molarity has the number of moles per liter (mol L-1). By convention, we use square brackets [ ] to represent molarity.
