A 500-m3/h (actual conditions) stream of an air-SO2 mixture containing 15% SO2 by volume at 20C and 1.0 atm is to be scrubbed with water (see figure below). Assume that the scrubber operates at constant temperature and pressure. If the scrubber is set up to remove 95% (by mass) of SO2 from the gas stream, calculate the mass flow rate of SO2 (kg/day) leaving the scrubber.
