A mixture of immiscible liquids (both water-insoluble) is subjected to steam distillation. At 90 degrees C, the vapor pressure of pure water is 526 mm Hg. If the vapor pressure of compound A is 127 mm Hg and that of B is 246 mm Hg at 90 degrees:
a) What is the total vapor pressure of the mixture at 90 degrees?
b) Would this mixture boil at a temperature above or below 90 degrees?
c) What would be the effect on the vapor pressure and boiling temperature by doubling the amount of water used?
