Over a 30-day period a power plant generates an average of 751 MW of electrical power and 1225 MW of waste heat, and burns 1.83×108 kg of coal. Assume that it takes 2.30 kg of oxygen to burn 1.00 kg of coal. (The actual amount varies with the type of the coal). What is the total mass of the reagents used in the combustion during the 30 days?
