Molce A gaseous mixture consisting of $20\%$ carbon disulfide $($CS$2)$ and $80\%$ air $($F$)$

It is fed to the absorption column to separate carbon disulfide at a rate of $1000$ Ibmol$/$hour$.$ CS$2$

most of the input is absorbed by liquid benzene $($L$)$ fed to the top of the column

$($absorbed$).2\%$ of the moles of benzene entering with L flow evaporate and leave the system with the exiting gas flow $($G$).$

walks away. The exit gas stream $($G$)$ in question consists of $96\%$ air, $2\%$ CS$2$ and $2\%$ benzene by mol.

while forming; The product liquid stream $($P$)$ consists of benzene and CS$2.$ Given and below

Considering the shape, the molar flow rates of $($G$),($L$)$ and $($P$)$ streams and the flow rates of the streams in question are

Determine their composition $($in mole fractions$)$
