Please can you assist me in answering this question.

19.6 [Himm (8th edition Hardcover) 5.5.8 on pp.262] Solvents emitted from industrial operations can become significant pollutants if not disposed of properly. A chromatographic study of the waste exhaust gas from a synthetic fibre plant has the following analysis in mole percent: CS2 SO2 H2O 40 % 10 % 50 % It has been suggested that the gas be disposed of by burning with an excess of air. The gaseous combustion products are then emitted to the air through a smokestack. The local 35 | Page air pollution regulations say that no stack gas is to analyse more than 2 % SO2 by an Orsat analysis averaged over a 24-hr period. Calculate the minimum percent excess air that must be used to stay within this regulation.
