A solution of benzene (CH) and toluene (C7Hs) is 29.0 benzene by mass. At 25°C the vapor pressures of pure benzene and pure toluene are 94.2 and 28.4 torr, respectively. Why is the composition of the vapor different from the composition of the solution? O O O The vapor will be richer in the less volatile component. The vapor will be richer in the component with a higher mass percent in solution. The vapor will be richer in the component with a smaller molar mass. The vapor will be richer in the component with a lower mass percent in solution. The vapor will be richer in the component with a greater molar mass. The vapor will be richer in the more volatile component. A solution of benzene (CH) and toluene (C7Hs) is 29.0 benzene by mass.
