Ethane (C₂H₆) is a minor component of natural gas. How much carbon dioxide (in grams) is produced from the complete combustion of 42.0 g ethane?
2 C₂H₆ + 7 O₂ $\rightarrow$ 4 CO₂ + 6 H₂O

Question

Ethane (C₂H₆) is a minor component of natural gas. How much carbon dioxide (in grams) is produced from the complete combustion of 42.0 g ethane? 2 C₂H₆ + 7 O₂ $\rightarrow$ 4 CO₂ + 6 H₂O

Quizplus · Accepted Answer

The molar mass of ethane (C2H6) is 30.07 g/mol. 42.0 g of ethane is 42.0 / 30.07 = 1.396 moles. The balanced equation shows that 2 moles of ethane produce 4 moles of CO2. Therefore, 1.396 moles of ethane will produce 2.792 moles of CO2. The molar mass of CO2 is 44.01 g/mol, so 2.792 moles of CO2 is 2.792 * 44.01 = 122.9 g, which rounds to 123 g CO2.
