Q$3)$ SL balance

Small amounts of VOCs such as acetone in a wastewater stream is to be removed by adsorption of activated carbon. The adsorption isotherm at room temperature is of the Langmuir type:

$q=\frac{0\mathrm{.}190*c}{1+0\mathrm{.}146*c}$

Where $q$ is amount of solute adsorbed, $mo\frac{l}{k}g,$ and $c$ is solute concentration in aqueous solution, $mo\frac{l}{m^3}.$

Acetone concentration is $45mo\frac{l}{m^3}$ at first, answer the following questions:

b$)$ Design a two$-$stage adsorption process, and acetone concentration in the second stage reaches $5mo\frac{l}{m^3},$ what does the total activate carbon needed in the two stages in $k\frac{g}{m^3}?$
