Nthe commercial production of sugar (sucrose), the product crystals are washed and centrifuged to partial dryness. the crystals are then sent through a rotary dryer where they are contacted with a hot stream of air that reduces the moisture content from 1.10 wt% to 0.100 wt%. the ratio of wet sugar to inlet air fed to the dryer is 3.30 kg wet sugar/kg inlet air. the inlet air contains 1.45 mole% water.

calculate the weight percent of water in the inlet air stream.
