Chemistry - Concentration Terms Question with Solution | TestHub

The mole fraction of a solute in a solution is$0.1$. At$298 \mathrm{K}$, the molarity of this solution is the same as its molality. The density of this solution at$298 \mathrm{K}$is$2.0\mathrm{ }\mathrm{g}\mathrm{ }\mathrm{c}{\mathrm{m}}^{–3}$. The ratio of the molecular weights of the solute and solvent,$\left(\frac{\mathrm{M}{\mathrm{W}}_{\mathrm{s}\mathrm{o}\mathrm{l}\mathrm{u}\mathrm{t}\mathrm{e}}}{\mathrm{M}{\mathrm{W}}_{\mathrm{s}\mathrm{o}\mathrm{l}\mathrm{v}\mathrm{e}\mathrm{n}\mathrm{t}}}\right)$, is:
