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

Explanation

By definition, molarity of a solution is defined as the number of moles of solute dissolved in one litre of solution. Thus, molarity takes into account the volume of the solution which changes with change in temperature. Hence, molarity is a function of temprature. On the other hand, all other terms used to express the concentration of a solution involve the mass of solvent which does not change with change in temperature.
