Assignment #3. The temperature of pure water at equilibrium vapor pressure of 36.2 torr is 45°C. When 30.4 g of a nonelectrolyte solute is dissolved in 40 g water, the vapor pressure of the solution is 3.20 lower than that of the pure water at the same temperature, what is the mole fraction, and molecular mass of the solute?

Define the terms in Raoults law. Figure 10-9 illustrates the net transfer of water molecules from pure water to an aqueous solution of a nonvolatile solute. Explain why eventually all of the water from the beaker of pure water will transfer to the aqueous solution. If the experiment illustrated in Fig. 10-9 was performed using a volatile solute, what would happen? How do you calculate the total vapor pressure when both the solute and solvent are volatile?
