A solution is composed of 1.90 mol cyclohexane (Py = 97.6 torr) and 2.10 mol acetone (Pac = 229.5 torr). What is the total vapor pressure Ptotal above this solution? Express your answer with the appropriate units. ► View Available Hint(s) Ptotal= 167 torr Submit Previous Answers 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 + XBPg + 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. ► View Available Hint(s)
