Into an evacuated 30-liter vessel is placed 0.1 mol of n-butane
dissolved in 0.9 mol of n-hexane. If the vessel and its contents
are kept at 298 K, what is the pressure and the vapor and liquid
compositions whenequilibrium is achieved? You may assume ideal
liquid and vapor behavior. Data at 298 K: The density of liquid
n-butane is 0.575 g/cc and its vapor pressure is 2.428 bar. The
density of liquid n-hexane is 0.655 g/cc and its vapor pressure is
0.200 bar.
