A )If 0.640mol ofa nonvolatile nonelectrolyte are dissolved in 3.40mol ofwater, what is the vapor pressure PH2O of theresulting solution? The vapor pressure of pure water is
23.8 torr at 25 ?C.
B) A solution is composed of 1.90mol cyclohexane(P?cy=97.6 torr) and 2.90mol acetone(P?ac=229.5 torr). What is the total vapor pressurePtotal above thissolution?
