Question 3: 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: x -0.30, y= 0.23, and P- 10.1 kPa. Use this information to estimate the system pressure and vapor-phase mole fraction when x - 0.8.
