It is found that dissolving 5.62 g of a substance in 975 g of carbon disulfide (CS2) at 293 K lowers the freezing point by 0.632 K. Note that Kc = 3.8 K kg mol-1, Keb = 2.37 K kg mol-1, Mm (CS2) = 76.141 g mol-1 and the density of carbon disulfide is 1.26 g cm-3. Calculate the elevation of the boiling point, the ratio of the vapor pressure above the solution to that of the pure solvent, the osmotic pressure and the molecular weight of the solute. P * (CS2) = 0.394 bar at 293 K
