Step-by-Step Solution
Molality is defined as the number of moles of solute dissolved per kilogram of solvent. Since both moles and mass of the solvent do not change with changes in temperature, molality is independent of temperature. On the other hand, molarity, normality, and formality involve volume, which changes with temperature.
