Calculate the vapor pressure (in atm) of pure water at 80.0°C. For water, ΔHvap = 40.7 kJ/mol, R = 8.314 J/K-mol

A chemistry student is given 250. mL of a clear aqueous solution at 44.° C. He is told an unknown amount of a certain compound X is dissolved in the solution. The student allows the solution to cool to 28.° C. At that point, the student sees that a precipitate has formed. He transfers the liquid to a clean new beaker and throws away the precipitate. The student then evaporates the water from the liquid in the new beaker under vacuum. It weighs 2.0 g. Using only the information above, can you calculate the solubility of Xin water at 28.° C ? If you said yes, calculate it. Be sure your answer has a unit symbol and the right number of significant digits.

Calculate the change in the chemical potential of liquid water and water vapor when the pressure is increased from 1.0 atm to 10 atm at 100°C. Discuss the effect of the pressure increase on the equilibrium between the liquid water and the water vapor. Assume that water vapor behaves perfectly and the density of water is 1 g/cm3.
