Cоаl is а leаding sоurce оf energy for the world. While coal is primarily composed of carbon and hydrogen., a small amount of sulfur is also present. This leads to the production of pollutants such as sulfur dioxide (SO2) through the following reaction: S(s) + O2 (g) --> SO2 (g) A sample of coal contains [x] % sulfur by mass. If [y] kg of this coal were burned, what mass of sulfur dioxide could theoretically be formed?
