Molarity vs Molality: Formula and Definitions
Both molarity and molality are measures of a chemical solution’s concentration. The primary difference between the two comes down to mass versus volume.
The molality describes the moles of a solute in relation to the mass of a solvent, while the molarity is concerned with the moles of a solute in relation to the volume of a solution.
Read on to learn more about molarity and molality, including their definitions, equations, and a comparison of the two terms.
Molality definition
Molality (m), or molal concentration, is the amount of a substance dissolved in a certain mass of solvent. It is defined as the moles of a solute per kilograms of a solvent. [Updated May 4, 2020].
Molality formula and units
The units of molality are m or mol/kg.
Molality equation
m = moles solute / kilograms
