Colligative properties of soln. 1. Calculate the boiling point and freezing point of 30 g sucrose (342) in 110 g water? 2. A 1.5 g sample was dissolved in 30 g water. The crystals were observed to start to form in this soln at -0.93 oC. Calc the MM of the compound. 3. The osmotic pressure of a soln containing 50 g of myoglobin in benzene in 10 mL of soln is 4.8 Torr at 5oC.What is the MM of myoglobin? 4. If 100 g of glycerine (92 g/mole) is mixed with 150 mL water , what is the v. pres of soln at 25 oC? (PH2O at 25 oC = 23.76 mm Hg)
