here is all the context, i only need part c done please

Correct Correct answer is shown. Your answer 179.07 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 + P3 + Pc = XA P + X3 PB + XcP8 a 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, Xcy (vapor), is cyclohexane? Express your answer numerically. View Available Hint(s) VO AS ] t ? Xcy(vapor) = Part A As the concentration of a solution increases, its vapor pressure decreases. For a nonvolati e soluto B in aliquid solvent A, the relationship between concentration and vapor pressure is expressed by Raoult's law P=X, Pi where PA is the vapor pressure of the solution XA is the mole fraction of solvent and P, is the vapor pressure of the pure solvent In a two-component solution consisting of A and B. the mole fraction.

The total vapor pressure is the sum of the partial pressures of the components Pol PA+ PixAP+XnP whore P, and P, are the vapor pressures of pure A and B, respectively. Part B As the concentration of a solution increases, its vapor pressure decreases. For a nonvolatile solute B in a liquid solvent A, the relationship between concentration and vapor pressure is expressed by Raoult's law PA=XAPR where in the vapor pressure of the solution XA is the mole fraction of solvent, and Pis the vapor pressure of the pure solvent. In a two-component solution consisting of A and B, the mole fraction, X, of component A is defined as A solution is composed of 1.30 mol cyclohexano (P; = 97.6 torr) and 2.10 mol acetone (P = 229.5 torr).
