Step 1

The values are given as follows: help_outlineImage Transcriptionclosemoles of acetone = 3.34 mol moles of cyclohexane = 1.45 mol - total moles 3.34 mol + 1.45 mol =4.79 mol vapor pressure of acetone(Ptone ) = 229.5 torr vapor pressure of cyclohexane(P cvelohexane ) =97.6 torr fullscreen
Step 2

The mole fraction of acetone in the solution can be calculated as follows: help_outlineImage Transcriptionclose(solution)= number of moles of acetone total number of moles х, aceton 3.34 mol 4.79 mol = 0.6973 fullscreen
