Tutorial $4($Adsorption$)$

Wet air containing $4\mathrm{.}0$ mole $\%$ water vapor is passed through a column of calcium chloride pellets. The pellets adsorb $97\mathrm{.}0\%$ of the water and none of the other constituents of the air. The column packing was initially dry and had a mass of $3\mathrm{.}40kg.$ Following $5\mathrm{.}0$ hours of operation, the pellets are reweighed and found to have a mass of $3\mathrm{.}54kg.$

Calculate the molar flow rate $(mo\frac{l}{h})$ of the feed gas and the mole fraction of water vapor in the product gas $($Draw and label a flowchart of the adsorption process and perform the degree$-$offreedom analysis prior to solving the problem$).$
