The boiling temperature of a substance increases by 0.63⁰C by dissolving 565 g of an organic solvent, consisting of 5.25 g of C and H, with a Ma of 78 and a density of 0.88 g/cm3, at 298K. Considering that this solvent is Kf = 5.12 K kg/mol and Kb = 2.53 K kg/mol, and its pure vapor pressure is 103 tons at 298K, find the freezing point drop, vapor pressure and osmotic pressure of the solvent in the solution.
