The vapour pressure of pure benzene is 22 mm and that of pure Toulene is 75 mm at 200C.What is the composition of the solution of these two components that has a vapour pressure of 50 mm at this temperature?What is the composition of vapour in equilibrium with this solution?

Com of Benzene=0.47
Comp. of Toulene=0.53
In vapour phase
Benzene=0.2068
Toulene=0.795
Is it correct??????????

Quite simple
Do ya 'now the fomula
Psol=Xb*Pb+Xt*Pt ( where b==benzene& t= toulene)
=> 50=22Xb+75(1-Xb)
solve it & u'll get the ans
& fr va. p.
Yb=Xb*Pb
       Psol
use the same fr Toulene.
