A mixture of 100 mol containing 60 mol % n-pentane and 40 mol% n-heptane is vaporized at 101.32 kPa abs pressure until 40 mol of vapor and 60 mol of liquid in equilibrium with each other are produced. This occurs in a single-state system, and the vapor and liquid are kept in contact with each other until vaporization is complete. Required:
Calculate the composition of the vapor and the liquid.
