A solution made of toluene and benzene is prepared with a mole fraction of 0.7 for toluene. If the vapor pressure of pure toluene is 70 torr, and the vapor pressure of pure benzene is 190 torr, what is the total ideal vapor pressure of this solution? A. 57 torr B. 49 torr C. 0.30 torr D. 106 torr Table sugar granules were dissolved in a glass of water. The solid sugar granules have no measurable vapor pressure, making water as the contributor to the entire vapor pressure of the resulting solution. If sugar was added to the glass of water until the water makes up a mole fraction of 0.75 in the solution, what is the total vapor pressure of the solution? Given the following: vapor pressure of water at 25°C is 23.8 torr. A. 23.8 torr B. 5.95 torr C. 29.75 torr D. 17.9 torr
