A power plant burns 150 U.S. short tons of coal per day as well as there are 18.2 lb. of flue gas produced per pound of coal. The sulfur content of the coal is 2.0 percent and the molar mass molecular weight of the flue gas is 30.5. If all the sulfur in the coal appears as SO2 in the flue gas, explain what is the concentration of SO2 in the flue gas in parts per million?
