  Problem 3  
 A and B form an ideal solution at 30 oC, with xA = 0.4, 614c2393293da.jpg
(Note: 614c23ca467b5.jpgis the vapor pressure of the corresponding pure substance. 614c23d2219df.jpg is the mole fraction of that component in the liquid)

(2) A portion of the gas phase is removed and condensed in a separate container. Calculate the partial pressures of A and B in equilibrium with this liquid sample at 30 ℃.
