At 90°C, the vapour pressure of methylbenzene is 54 kPa and that of 1,3-dimethylbenzene is 18.0 kPa. What is the molar fraction of methylbenzene in the gas phase above the mixture containing 1 mol of methylbenzene and 2 mol of 1,3- dimethylbenzene at this temperature (assume that these solvents form ideal solutions).
