10. A 0.20 M solution of MgSO4 has an observed osmotic pressure of 7.8 atm at 25° C. Determine the observed van't Hoff factor, i, for this experiment. 3 11. The osmotic pressure of human blood is 7.6 atm at 37°C, which is normal body temperature. What mass of glucose (C6H12O6, molar mass = 180.2 g/mol) is required to make 1.00 L of aqueous solution for intravenous feeding if the solution must have the same osmotic pressure as blood at body temperature, 37°C? 12. A solution was prepared by dissolving 1.000 g of an unknown non-electrolyte in 50.00 g of CCl4. The freezing point of the solution was found to be -28.4°C. What is the molar mass of this unknown solute? (The freezing point of pure CCl4 is -22.3°C, and K for CCl4 is 29.8°C-kg/mol.)
