Ethane (C2H6) is mixed with oxygen to obtain a fuel gas containing 80% ethane and 20% oxygen. The fuel gas is burned with 200% exsuess air. Note that fuel contains oxygen. Eighty perecent of ethane goes to produce carbon dioxide, 10% to carbon monoxide and 10% remains undurned. Calculate the compostion of the exhaust gas on a wet basis.
