A solution contains 50.0 g of heptane (C 7 H 16 ) and 50.0 g of octane

Question:

A solution contains 50.0 g of heptane (C₇H₁₆) and 50.0 g of octane (C₈H₁₈) at 25 °C. The vapor pressures of pure heptane and pure octane at 25 °C are 45.8 torr and 10.9 torr, respectively.

Assuming ideal behavior, answer the following:

a. What is the vapor pressure of each of the solution components in the mixture?

b. What is the total pressure above the solution?

c. What is the composition of the vapor in mass percent?

d. Why is the composition of the vapor different from the composition of the solution?
