The world burns approximately 9.0x10^2 kg of fossil fuel per year. Use the combustion of octane as the representative reaction and determine the mass of carbon dioxide(the most significant greenhouse gas) formed per year by this combustion. The current concentration of carbon dioxide in theatmosphere is approximately 387 ppm (by volume). By what percentage does the concentration increase in one year due to fossil fuel combustion? Approximate the average properties of the entire atmosphere by assuming that the atmosphere extends from sea level to 15 km and that it has an average pressure of 381 torr and average temperature of 275 K. Assume Earth is a perfect sphere with a radius of 6371 km.
