Calculate the activities and activity coefficient for an acetone$-$choroform solution in which x$2=0\mathrm{.}6.$ The vapor pressure of pure chloroform at $323$K is P$*2=98\mathrm{.}6$Kpa and the vapor pressure above the solution is P$2=53\mathrm{.}5$Kpa. For acetone, the corresponding values are P$*1=84$Kpa and P$1=26\mathrm{.}6$Kpa
