In 1986 an electrical power plant in Taylorsville, Georgia, burned 8,376,726 \rm tons of coal, a national record at that time.
Assuming that the coal was 86.0 \% carbon by mass and that combustion was complete, calculate the number of tons of carbon dioxide produced by the plant during the year.
Assuming that the coal was 4.50 \% sulfur by mass and that combustion was complete, calculate the number of tons of sulfur dioxide produced by the plant during the year.
