Vapour pressure of C6H6 and C7H8 mixture at 50°C is given by P (mm Hg) = 179XB + 92, where XB is the mole fraction of C6H6 . A solution is prepared by mixing 936 g benzene and 736 g toluene and if the vapours over this solution are removed and condensed into liquid and again brought to the temperature of 50°C, what would be mole fraction of C6H6 in the vapour state?

Step-by-step explanation:
We know the equation
P= PoA +Xb (PoB -PoA)
Po Tol = 92
Po Ben = 179+92 = 271
n ben = 936/78
n tol = 736/92
Solving we get
X ben = 0.92

Step-by-step explanation:
TO FIND:
Mole fraction of in the vapour state
Vapour pressure of C6H6 and C7H8 mixture at 50°C is given by , where XB is the mole fraction of C6H6.
A solution is prepared by mixing 936 g benzene and 736 g toluene and if the vapours over this solution are removed and condensed into liquid and again brought to the temperature of 50°C.
=271, =92
On additional buildup
,
Mole fraction of in the vapour state is 0.9286
