Enter the molecular weight, volume, and moles into the calculator to determine the molarity of your solution.

Molarity Calculation Formula

The formula used to calculate molarity is:

Molarity (M) = Moles (mol) / Volume (L)

Variables:

  • Molarity (M) is the concentration of a solution expressed as the number of moles of solute per liter of solution.
  • Moles (mol) is the amount of substance in the solution.
  • Volume (L) is the total volume of the solution.

To calculate molarity, divide the number of moles of solute by the volume of the solution.
