Correct
Correct answer is shown. Your answer 166.85 torr was either rounded differently or used a different number of
significant figures than required for this part.
If a third volatile component had been present in this solution, the total pressure would be calculated in a similar
manner but would involve three terms rather than two. For example,
Ptotal = PA + PB + Pc = XAPA + Xв PÅ + XcPc
Part C
As you saw in Part B, the vapor above the cyclohexane-acetone solution is composed of both cyclohexane vapor and
acetone vapor. What mole fraction of the vapor above the solution, Xey (vapor), is cyclohexane?
Express your answer numerically.
