At 20 degrees C the vapor
pressure of benzene (C6H6) is 75
torr, and that of toluene (C7H8) is
22 torr. Assume that benzene and
toluene form an ideal solution
(obey Raoult's Law). What is the
composition in mole fractions of a
solution that has a vapor pressure
of 35 torr at 20 degrees Celsius? *
C6H6 =
0.2984; C7H8 = 0.7016
C6H6 = 0.3689; C7H8 = 0.6311
C6H6 = 0.4012; C7H8 = 0.5988
C6H6 = 0.2453; C7H8 = 0.7547
