The Rast method uses camphor (C10H16O) as a solvent for determining the molar mass of a compound. When 2.50 g of cortisone acetate are dissolved in 50.00 g of camphor (k f =40.0C/m), the freezing point of the mixture is 173.44C; that of pure camphor is 178.40C. What is the molar mass of cortisone acetate?
