# Problem: The world burns approximately 3.7 x 1012 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. The current concentration of carbon dioxide in the atmosphere is approximately 399 ppm (by volume).

Balanced combustion of octane will appear as:

C8H18 (g) + 25 O2 (g) → 16 CO2 (g) +  18 H2O (g)

Calculating the COproduced every year:

86% (83 ratings)
