A very small amount of non-volatile solute (That does not dissociate) is dissolved in 56.8 $cm^3$ of benzene (density = 0.889 g $cm^{-3}$). At room temperature, vapour pressure of the solution is 98.88 mm Hg while that of benzene is 100 mm Hg. Find the molality of the solution. If the freezing point of the solution is 0.73 degree lower than that of benzene, what is the value of $K_f$ for benzene?
