Question:

A single vapor–liquid equilibrium point for the water (1) + ethanol (2) system is experimentally measured at 30°C. The experiment provides the following information: x₁ = 0.30, y₁ 5 0.23, and P = 10.1 kPa. Use this information to estimate the system pressure and vapor-phase mole fraction when x₁ = 0.8.
