Both molarity and molality are measures of a chemical solution’s concentration. The primary difference between the two comes down to mass versus volume. Read on to learn more about molarity and ...

Unlike molarity, molality does not change with temperature, making it a useful tool for various calculations in chemistry. In this article, we will explore how to calculate the molality of a solution ...

Molality (m) = Moles of solute / Mass of solvent in kg For example, 1.00 mol kg–1 (or 1.00 m) solution of KCl means that 1 mol (74.5 g) of KCl is dissolved in 1 kg of water.
