Answer:
The composition of benzene is 0.77 and the composition of toluene is 0.23
Explanation:
The Raoult´s law is:

Where
P = total pressure of solution benzene-toluene
PA⁰= vapor pressure of benzene = 95 torr
PB⁰ = vapor pressure of toluene = 28 torr
xA = mole fraction of benzene
xB = mole fraction of toluene

The total pressure of the solution is:

The composition of benzene and toluene:
