Suppose the combustion of fossil fuels adds about 8.0 $\times$ 10¹² kg of carbon to the atmosphere per year in the form of CO₂.How much oxygen gas is required to produce this amount of carbon dioxide?

Question

Quizplus · Accepted Answer

The combustion of carbon to form CO2 requires one mole of O2 for each mole of carbon. The molar mass of carbon is 12 g/mol, and the molar mass of O2 is 32 g/mol. Therefore, for 8.0 x 10^12 kg of carbon, the required oxygen is (32/12) times that mass, which is approximately 2.1 x 10^13 kg.

Suppose the Combustion of Fossil Fuels Adds About 8 ×\times× 1012 Kg of Carbon to the Atmosphere Per Year in 1012
