Wet air containing 5.0 mole% water vapour is passed through a column of calcium chloride pellets. The pellets adsorb 95% of the water and none of the other constituents of the air. The column packing was initially dry and had a mass of 3.40 kg. Following 5.0 hours of operation, the pellets are reweighed and found to have a mass of 3.54 kg.
