When coal is burned, carbon atoms are moved from the geosphere to the atmosphere. Each atom of carbon in the coal combines with two atoms of oxygen to produce carbon dioxide (CO2). Carbon dioxide has an atomic weight of 44, which is approximately 3.667 times heavier than a carbon atom of atomic weight 12. It takes about 4750 pounds of coal to power a house for one year. If anthracite coal is used, how many pounds of carbon will this be?
