A power plant burns coal and generates an average of 660.0 Megawatts (MW) of electrical power while discharging990.00 MW as waste heat. Find the total electrical energy generatedby the plant in a 30-day period.

Coals vary a lot in their energy content. Theenergy released by the burning of coal is typically between 23 and33 Mega Joules per kg of coal. The power plant above uses coalrated at 25.3 MJ/kg to heat the boilers. Some of that heat isconverted to electrical energy, but most is waste heat dischargedinto the environment. Assume that it takes about 2.26 kg of oxygen to burn 1 kg of coal (The actual amount varies with the type coal).Find the total mass of the reagents used in operating for 30days.
