Toluene (C6H5CH3) and benzene (C6H₁) are two organic liquids with very similar properties, and when they are mixed, they form an ideal solution. A mixture contains 35,6 g of toluene and 125 g of benzene. Toluene has a vapour pressure of 22 mm Hg, and benzene has a vapour pressure of 75 mm Hg at 25°C. (a) Which compound, toluene or benzene, would have the highest boiling point? Motivate your answer. (b) Calculate the total vapour pressure over the mixture at 25°C.
