Answer to Question #182496 in General Chemistry for Eden

Question

At 25°C, the vapor pressure of benzene, C6H6, is 95 torr, snd toluene, C7H8, is 28 torr. Find the total pressure of the solution containing 30% C6H6 and 70% C7H8.

Answer 1

X benzene = 0.30

X toluene = 0.7

P sol =(X benzene × P benzene) + (X toluene × P toluene)

= 0.3 × 95 + 0.7 × 28

= 28.5 + 19.6

= 48.1 torr
