Three 1.0- flasks, maintained at 308 , are connected to each other with stopcocks. Initially the stopcocks are closed. One of the flasks contains 2.0 of , the second 3.7 of , and the third, 0.10 of ethanol. The vapor pressure of at 308 is 42 and that of ethanol is 102 . The stopcocks are then opened and the contents mix freely.
