Solutions containing volatile solutes
In solutions composed of two liquids (A and B), each liquid contributes to the total vapor pressure above the solution. The total vapor pressure is the sum of the partial pressures of the components:
Ptotal=PA+PB=XAPâA+XBPâB
where PâA and PâB are the vapor pressures of pure A and B, respectively.
Part B
A solution is composed of 1.50 mol cyclohexane (Pâcy=97.6 torr) and 2.40 molacetone (Pâac=229.5 torr). What is the total vapor pressure Ptotal above this solution?
