Molarity to Molality Converter

Convert solution molarity to molality using the solution density and solute molar mass. Needed when temperature changes make volume-based concentration unreliable.

Molarity (M)

Solution density (g/mL)

Solute molar mass (g/mol)

Fill in the required fields to see your result.

Chemistry

Molarity Calculator

Calculate molar concentration (molarity, M) of a solution from moles of solute and total solution volume in litres. The most common concentration unit in chemistry, essential for stoichiometry, titrations, dilutions, and any lab calculation involving solutions.

Moles of solute (mol)

Volume of solution (L)
