Mass Molarity Calculator

Calculate the molarity of a solution from mass, molar mass, and volume

Formula

Molarity (M) = (Mass / Molar Mass) / Volume

M = (g / g·mol⁻¹) / L = mol·L⁻¹

Mass of Solute (g)

Molar Mass (g/mol)

Volume of Solution (L)

About Molarity

Molarity (M) is a measure of concentration expressed as moles of solute per liter of solution. It's one of the most common units used in chemistry to describe solution concentrations. To calculate molarity, first determine the number of moles by dividing the mass by the molar mass, then divide by the volume in liters.
