Problem

The ratio of vapour pressure of two miscible liquids

A

and

B

in pure state are in the ratio 1 : 3 respectively at a temperature.

n_A

mole of

A

and

n_B

mole of

B

are mixed to form an ideal solution. If the ratio of mole of

A

and

B

in vapour phase was found to be 4 : 3, the ratio of mole of

A

and

B

in which they are mixed was : a.

\frac{4}{5}

b. 4 c.

\frac{2}{3}

\frac{1}{3}
