1. Calculate the boiling point of a solution containing 12g glucose C6H12O6 dissolved in 200g of water H2O. (0.512°C - Kb of H2O) 2. Calculate the normal freezing point of a 0.7439 mol aqueous solution of C12H22O11 that has a density of 1.35 g/ml. (C12H22O11 is a non-volatile non-dissociating solute). The molal freezing point depression constant of water is 1.86°C kg/mole. 3. When 0.279 g of a molecular compound, benzoic acid, was dissolved in 43.0 g of benzene, the freezing point of the solution was lowered to 5.15°C. What is the molecular weight of the benzoic acid? (Note: Kf for benzene = 5.12°C/m; Freezing point of benzene = 5.5°C)
