**Explanation:**

The given data is as follows.

Vapour pressure of pure = 33.85 Torr

Temperature = 298 K

Mole fraction of = 122.36 torr

Therefore, calculate the vapor pressure of as follows.

Vapour pressure of = mole fraction of x K of

= 0.050 x 122.36 Torr

= 6.118 Torr

So,** vapor pressure of is 6.118 Torr
.**

Now, calculate the vapor pressure of carbon tetrachloride as follows.

Vapour pressure of = mole fraction of x Pressure of

= (1 - 0.050) × 33.85 Torr

= 32.1575 Torr

So,** vapor pressure of is 32.1575 Torr .**

Hence, the total pressure will be as follows.

= 6.118 Torr + 32.1575 Torr

= 38.2755 Torr

Therefore, composition of =

= 0.8405

**Composition of is 0.8405
.**

And, composition of =

= 0.1598

**Composition of is 0.1598
.**
