Question
3. The chemical potential of pure benzene decreases by 250 J when an amount of paraffin wax is dissolved in it at 25°C and 1 atm. At what temperature does this solution boil? M(Benzene) : 78.11 g/mol. Boiling point of pure benzene: 80.1°C. Boiling point constant of benzene: K= 2.53 K kg/mol 4. The osmotic pressure of a glucose solution is 5 bar when measured against water at 25°C. Calculate the vapor pressure lowering of water (The decrease in the vapor pressure of water comparing to pure water). Assume that the density of the glucose solution is 1 g/cm3. The vapor pressure of pure water at 25°C is 3167 Pa. MGlucose:180.16 g/mol
