Question
Part C & A please!!
where Paand FB are the vapor pressures of pure A and B, respectively Part B A solution is composed of 1 80 mol cyclohexane (F pressure Potal above this solution? Express your answer with the appropriate units. = 97.6 torr) and 2.10 mol acetone (P-229.5 torri whats the ttal vapor Hints Plotal 169 torr Submit My Answers Give Up Correct If a third volatle 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, 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 HintsExplanation / Answer
C) in part B ptotal = 169 torr
Ptotal = XaPa0 + XbPb0
mole fraction of a = moles of a / total moles of all compound
mole fraction of cyclohexane = 1.8 moles / (2.1 + 1.8 ) moles
Xcy = 0.4615
A)
2H3PO4 ----> P2O5 + 3H2O
The averege rate of formation of P2O5 = change in concentration / change in time
rate of formation of P2O5 = [ ( 8.2 - 2.2) 10-3 M / ( 40.0 - 10.0 ) s ]
rate of formation of P2O5 = 2.0x10-4 M/s
