6. Chlorobenzene and bromobenzene have similar structures and molecular dipole moments. Therefore, these two compounds can form an ideal solution. Given that the vapor pressures of pure chlorobenzene and bromobenzene at 25°C are
= 8.8 Torr,
= 4.2 Torr, respectively, calculate the molar fraction of bromobenzene in the vapor phase for a 1:4 chlorobenzene/bromobenzene solution.
