4. In an experiment, 3.2 grams of benzene and 3.2 grams of toluene are placed in a small closed container at 35C and allowed to come to equilibrium. What is the mole fraction of toluene in the vapor phase? a. How many moles of benzene are present in the mixture? b. How many moles of toluene are present in the mixture? c. In the mixture, what is the mole fraction w.r.t. toluene? I d. In the mixture, what is the mole fraction w.r.t. benzene? e. What is the vapor pressure in the mixture due to benzene? f. What is the vapor pressure in the mixture due to toluene? g. What is the mole fraction in the vapor w.l.t toluene? h. Is the toluene more of less enriched in vapor compared to the mixture
