Which of the following unit of concentration is independent of temperature ?

A. Molarity
B. Molality
C. Mole fraction
D. all

¨       Molality is independent of temperature as it is defined as the number of moles of solute per kilogram of solvent. The mass of solvent (in kg) remains constant regardless of temperature, therefore, molality remains the same regardless of temperature.

¨       Molarity and mole fraction are dependent on temperature because they are defined based on the volume and number of moles of solute and solvent, respectively.
