Problem: A particular coal contains 2.5% sulfur by mass. When this coal is burned, the sulfur is converted into sulfur dioxide gas. The sulfur dioxide reacts with solid calcium oxide to form solid calcium sulfite.If the coal is burned in a power plant that uses 2100 tons of coal per day, what mass of calcium oxide is required daily to eliminate the sulfur dioxide?
