The vapour pressure of two liquid P and ...

The vapour pressure of two liquid P and Q are 80 torr and 60 torr respectively. The total vapour pressure obtained by mixing `3` moles of P and 2 mole of Q would be

68 torr

20 torr

140 torr

72 torr

Text Solution

Verified by Experts

The correct Answer is:

`P_(T)=P_(P)xxP_(Q)=P_(P)^(@)xxP+P_(Q)^(@)xxQ`
`P_(T)=80xx(3)/(5)+60xx(2)/(5)=48+24=72` torr
