Although coal is a complex mixture of substances, its elemental composition can be approximated by the formula C135H96O9NS. Using this formula, predict the amount of CO2 released from the combustion of 1.00 × 106 metric tons of coal (about the annual average for a coal-fired power plant). 1 metric ton = 1 ×103 kg.
