How do you calculate the χacetone and χcyclohexane in the vapor above the solution. P°acetone = 229.5 torr and P°cyclohexane = 97.6 torr?
A solution is prepared by mixing 4.40 mol of acetone with 1.45 mol of cyclohexane at 30°C.

Well by definition....the vapour pressure of EACH component is PROPORTIONAL to
Explanation:
Well in solution, the
So,
And clearly....
And so
But in the vapour phase, the vapour pressure of EACH component is PROPORTIONAL to
As always, the vapour pressure is ENRICHED with respect to the more volatile component....here acetone...
