A mixture consists of 78,1 g benzene (C6H6) and 92,1 g toluene (C7H8). Both substances are volatile, and their vapour pressures (in the pure form) are as follows at 20°C: Benzene: 0.0988 atm Toluene: 0.0287 atm a) Which substance, benzene or toluene, would have the lowest boiling point in the pure form? Give a reason or your answer. b) Calculate the vapour pressure of the benzene-toluene mixture at 20°C
