Vapour pressure of pure A = 100 torr, moles = 2, vapour pressure of pure B = 80 torr, moles = 3 Total vapour pressure of mixture is

A

440 torr

B

460 torr

C

180 torr

D

88 torr

Text Solution

Verified by Experts

The correct Answer is:
D

`P_(Total) = P_Ax_A + P_Bx_B`
`100 xx2/5 +80 xx 2/3 = 88` torr
