1. A mixture of immiscible liquids (both water-insoluble) is subjected to steam distillation. At 90°, the vapor pressure of pure water is 526 mm Hg. If the vapor pressure of compound A is 127mm Hg and that of B is 246 mm Hg at 90°:

(a) What is the total vapor pressure of the mixture at 90°?

(b) Would this mixture boil at a temperature above or below 90°?

(c) What would be the effect on the vapor pressure and boiling temperature by doubling the amount of water used?
