Question 1: A mixture contains 79.0 g of water and 21.0 g of sucrose (C12H22O11). The partial pressure of pure water at 45.0 °C is 71.9 mm Hg. Find the mole fraction of the solute, the mole fraction of the solvent and the vapor pressure of the solution at 45.0
°C. Assume sucrose is a non-volatile substance.

Question 2: My bottle of Duff beer has an alcohol content of 8.0% by weight. Find the molality, the mole fraction of the solute, the mole
fraction of the solvent and the molarity of the beer. The density of Duff beer is 0.9976 g/cm3. Assume the beer consists only
of water and ethanol
