Arizona was the site of a 400,000-acre wildfire in June 2002. How much carbon dioxide was produced by this fire? Assume that the density of carbon on the acreage was 10 kg/m² and that 50% of the biomass burned (10,000 m² = 2.47 acre)

The correct answer is A.The density of carbon on the acreage was 10 kg/m2, and 50% of the biomass burned (10,000 m2 = 2.47 acre). So, the total amount of carbon burned was 10 kg/m2 * 0.5 * 400,000 acres * 2.47 acres/10,000 m2 = 3 * 10^10 kg.
