Question
Part B 229.5 torr). What is the total vapor pressure Petal A solution is composed of 1.50 mol cyclohexane (Py = 97.6 torr) and 2.50 mol acetone (Pc above this solution? Express your answer with the appropriate units Hints Potal = 180 torr Submit My Answers Give Up Correct 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 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 Hints | Xy(vapor)= 10.375 Submit My Answers Give Up Incorrect; Try Again; 5 attempts remaining ContinueExplanation / Answer
Partial vapour pressure of cyclohexane=97.6 torr p
Total vapour pressure=180 torr=P
From the below relation,we have
Partial vap pressure of substance=
mole fraction of substance x total vapour pressure
=>p= P x mole fraction
=>97.6 torr = mole fraction x 180 torr
=> Mole fraction=97.6 torr/180 torr
=>Mole fraction=0.542
