2. A gas whose composition is 12.54% mol carbon
disulfide, 17.80% mol oxygen, and 69.66% mol nitrogen
is introduced into an absorber. In it, most of the
carbon disulfide is absorbed in liquid benzene fed to
the top of the tower. Some of the benzene that
enters as a liquid evaporates and leaves the top of
the tower as a vapor. If the gas leaving the tower
contains 2% carbon dioxide and 4% benzene, what is
the fraction of carbon dioxide recovered?
