The vapour pressure of two pure liquids ...

The vapour pressure of two pure liquids (A) and (B) are 100 and 80 torr respectively. The total pressure of solution obtained by mixing 2 mole of (A) and 3 mole of (B) would be :-

A

120 torr

B

36 torr

C

88 torr

D

180 torr

Text Solution

Verified by Experts

The correct Answer is:
C
`P_m=P_A^@X_A + P_B^@X_B`
`=100xx2/5+80xx3/5`
=40+48=88 torr
