molality
Sign in to saveAlso known as molal concentration
In chemistry, molality is a measure of the amount of solute in a solution relative to a given mass of solvent. This contrasts with the definition of molarity which is based on a given volume of solution.

In chemistry, molality is a measure of the amount of solute in a solution relative to a given mass of solvent. This contrasts with the definition of molarity which is based on a given volume of solution.
A commonly used unit for molality is moles of solute per kilogram solvent (mol/kg). A solution of concentration 1 mol/kg is often written as 1 molal (or 1 m).
