In this case, according to the Raoult's law, we can find the mole fraction of 79 wt% benzene and 21 wt% toluene at 50 °C in the vapor phase as follows:
However, we first have to calculate the mole fractions in the solution as follows (b stands for benzene and t for toluene):
Next, we calculate the total pressure as follows, according to the Dalton's law:
Finally, the mole fractions of the vapor phase turn out:
