A solution of benzene (C6H6) and toluene (C7H8) is 25.0% benzene by mass. At 25 °C the vapor pressures of pure benzene and pure toluene are 94.2 torr and 28.4 torr, respectively. Assuming ideal behavior, calculate the following:(a) The vapor pressure of each of the solution components in the mixture.(b) The total pressure above the solution.(c) The composition of the vapor in mass percent.Why is the composition of the vapor different from the composition of the solution?
