Liquids A and B form an ideal solution. (a) At -45◦C the vapor pressure of pure A and pure B is 0.09 and 0.12 atm, respectively. If we combine A and B such that it contains 36% (by concentration) of A at this temperature, calculate the composition of vapor. (b) You prepare a new solution from A and B. The boiling point of this solution is 88◦C. At this temperature, the vapor pressures of pure A and B is 0.50 and 1.26 atm, respectively. What is the initial composition of the vapor, just before it starts to boil?

Question
Liquids A and B form an ideal solution.
(a) At -45◦C the vapor pressure of pure A and pure B is 0.09 and 0.12 atm, respectively. If we combine
A and B such that it contains 36% (by concentration) of A at this temperature, calculate the
composition of vapor.
(b) You prepare a new solution from A and B. The boiling point of this solution is 88◦C. At this
temperature, the vapor pressures of pure A and B is 0.50 and 1.26 atm, respectively. What is the
initial composition of the vapor, just before it starts to boil?
