Q.You have 10 g of polystyrene dissolved in benzene and the volume of this solution is 1L. The density of this solution is 0.88 g/cm3. This solution is contained in the osmometer under 1 atm external pressure. The equilibrium height of the column (h) of solution is 11.6 cm at 25 °C. What is the average molar mass of the polystyrene? Assume that the solution is ideal and follows van't Hoff equation. The acceleration due to the gravity, g is 9.8 m/s2.
