(A) Mole fraction and molality are independent of temperature.

WitrynaWhen the temperature increases the molarity of the solution will decrease as temperature depends on volume. Molality is the number of moles of solute per kilogram solvent. Thus in case of molality, the number of moles of solute and solvent are both independent of temperature. So, there is no effect of temperature on molality.
