Concentration terms such as mass percentage, ppm, mole fraction and molalityare independent of temperature, however molarity is a function of temperature.
Explain.
Out of these, mass%, mole fraction, ppm and molality are independent of temperature because number of moles of a component and mass of solution or solvent doesnot change with temperature. Whereas, molarity is temperature dependent since volume is temperature dependent. The volume of most the substances increase with the increase in temperature. Hence, the quantities which are volume dependent depend on temperature also.
