An ideal solution contains two volatile liquid

A

(

P^0 = 100 \text{ torr}

) and

B

(

P^0 = 200 \text{ torr}

). If liquid mixture contains 1 mole of

A

and 4 mole of

B

then total vapour pressure of the mixture obtained by condensing the vapour above this solution in a beaker is : (1) 180 (2) 188.8 (3) 178.8 (4) 198.8
