WebFreezing-point depression depends on the concentration of the solute. The molality of the solution is a measure of concentration and is defined as: molesof solute molality= kilogramsof solvent Unlike molarity, molality does not depend on temperature because the mass of the solvent doesn’t change with temperature. WebUnlike molarity, which depends on the volume of the solution, molality depends only on the mass of the solvent. Since volume is subject to variation due to temperature and pressure, molarity also varies by temperature and pressure. In some cases, using weight is an advantage because mass does not vary with ambient conditions.
