Question

1. Calculate the molecular weight of the solute in a solution containing 2.47 g of a non-volatile solute in 100 g of acetic acid (CH3COOH) freezes 1.3°C below the normal freezing point for pure acetic acid (kf = 3.9) 2. If an aqueous solution of a non-volatile, non-electrolyte freezes at -1.28°C, what is its boiling point temperature? 3. The vapor pressure of pure water at 110°C is 1070 torr. A solution of ethylene glycol and water has vapor pressure of 1.00 atm at 100°C. Assuming that Raoult's law is obeyed, what is the mole fraction of ethylene glycol in the solution? 4. Automotive antifreeze consists of ethylene glycol, C2H6O2, a non-volatile non-electrolyte. Calculate the boiling point and freezing point of a 25.0 mass percent solution of ethylene glycol in water. 5. Calculate the freezing point of a solution containing 0.600 kg of CHCl3 and 42.0 g of eucalyptol, C10H18O, a fragrant substance found in the leaves of eucalyptus trees. Normal freezing point of CHCl3 is -63.5°C and Kf is 4.68 °C/m
