Molarity Calculator

The molarity calculator helps you calculate the mass required in grams for the molar solution.

Enter the formula weight, desired final volume, and desired concentration to determine the mass required.

The calculator also allows you to switch the desired final volume units from Litres to milliliters and microliters.

You can also switch the units of desired concentration from molar to Millimolar, Micromolar, Nanomolar, Picomolar, and Femtomolar.

In case you don’t know, molarity is the amount of a solute per liter of a solution in moles. Molarity is also called a solution’s molar concentration.

M = n/V

Where n = moles, V = volume of the solution
