In another day John has to measure the molar mass of a biological sample. Because the sample is not stalble at high or low temperatures, he decides to use osmosis to do the measurement. He adds different amount of the sample in 100 g of water against the other side of the osmometer pure water at room temperature 298.15 K. The pressure difference is measured and listed below.

Two volatile liquids A and B form an ideal solution. The vapor pressures for the pure liquids (at T = 50.0 °C) are pA° = 418. torr and pB° = 226. torr. For a solution at T = 50.0 °C, it is found that pA = pB. Based on this information, find XA, the mole fraction of A in the liquid phase for the solution.
