Two solutions of `A` and`B` are available. The first is known to contain `1` mole of `A` and `3` moles of `B` and its total vapour pressure is `1.0` atm. The second is known to contain `2` moles of `A` and `2` moles of `B`, its vapour pressure is greater than `1` atm, but if is found that this total vapour pressure may be reduced to `1` atm by the addition of `6` moles of `C`. The vapour pressure of pure `C` is `0.80` atm. Assuming ideal solutions and that all these data refered to `25^(@)C`, calculate the vapour pressure of pure `A` and `B`.

A 300 K the vapour pressure of an ideal solution containing 1 mole of liquid A and 2 moles of liquid B is 500 mm of Hg. The vapour pressure of the solution increases by 25 mm of Hg if one more mole of B is added to the above ideal solution at 300 K. Then vapour pressure of A in its pure state is :

The vapour pressure of pure liquid A is 0.80 atm. On mixing a non-volatile B to A, its vapour pressure becomes 0.6 atm. The mole fraction of B in the solution is:
