Problem: The vapor pressure of carbon tetrachloride, CCl4, is 0.354 atm and the vapor pressure of chloroform, CHCl3, is 0.526 atm at 316 K. A solution is prepared from equal masses of these two compounds at this temperature.Calculate the mole fraction of the chloroform in the vapor above the solution.

FREE Expert Solution

We have to calculate the mole fraction of chloroform in the vapor above solution.


The mole fraction of a component in the vapors above the solution is calculated using this formula:

Xa = PaPt

Where,

Xa = mole fraction of a component in vapors above solution

Pa = vapor pressure of a component of solution

Pt = total vapor pressure
