Vedclass · Answer

(D) Concentration terms that involve volume are temperature-dependent because volume changes with temperature.$1$. Molality $(m)$ is defined as the number of moles of solute per kilogram of solvent: $m = \frac{n_{	ext{solute}}}{W_{	ext{solvent}} 	ext{ (in kg)}}$. Since mass $(W)$ is independent of temperature,molality is temperature-independent.$2$. Mole fraction $(x)$ is the ratio of the number of moles of one component to the total number of moles in the solution: $x_A = \frac{n_A}{n_A + n_B}$. Since the number of moles is independent of temperature,the mole fraction is temperature-independent.$3$. Normality $(N)$ involves volume of solution $(V)$,which changes with temperature.Therefore,both mole fraction and molality are independent of temperature.

Which of the following concentration terms does not change with a change in temperature?
