At `300 K`, the vapour pressure of an ideal solution containing one mole of `A` and `3` mole of `B` is `550 mm` of `Hg`. At the same temperature, if one mole of `B` is added to this solution, the vapour pressure of solution increases by `10 mm` of `Hg`. Calculate the `V.P.` of `A` and `B` in their pure state.

Text Solution

Verified by Experts

The correct Answer is:
`V.P.` of `A = 400 mm`, `V.P.` of `B = 600 mm`;
