Concentration terms such as mass percentage,

Question:

 Concentration terms such as mass percentage, ppm, mole fraction and molality are independent of temperature, however, molarity is a function of temperature. Explain.

Solution:

A change in temperature causes a change in volume, therefore changes the molarity of a solution. Hence, terms such as mass percentage, ppm, mole fraction, and

molality are independent of temperature as they are calculated based on mass and do not involve volume.
