g A solution containing 3.6 mol of benzene ( C6H6 , b. p. 80°C) and 5.4 mol of toluene (C6H5CH3 , b. p 110°C) is placed in a closed container at 35°C. Some evaporation takes place. What is the mole fraction of toluene in the vapor phase when equilibrium is reached? At 35°C, vapor pressures are: benzene 160. torr, toluene 50.0 torr. HINT: Use Raoult’s Law to find the total vapor pressure, then calculate the fraction of the pressure that is due to toluene vapor. A) 0.52 B) 0.67 C) 0.33 D) 0.14 E) 0.60
