Material balance:
A gas containing equal parts (on a molar basis) of H2, N2, and H2O is passed through a column of calcium chloride pellets, which absorb 97% of the water but none of the gases. The column packing was initially dry and had a mass of 2.00 kg. Following 6 h of continuous operation, the pellets are reweighed and are found to have a mass of 2.21 kg.
Calculate the molar flow rate (mol/h) of the feed gas and the mole fraction of water vapor in the product gas.
