Molarity Result

Enter mass, molar mass, and volume to calculate molarity.

Description

Molarity (M) is the number of moles of solute per liter of solution, expressed in mol/L. It is one of the most common concentration units in chemistry. Formula: M = n / V = (mass / molarMass) / volume(L).

How to use

Enter the solute mass in grams, the molar mass in g/mol (use the Molar Mass Calculator if needed), and the solution volume in mL. The molarity is calculated instantly.
