Question #182496
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.
Expert's answer
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
