24.0 g of ethane (C₂H₆) are burned to form CO₂ and H₂O. How many grams of CO₂ are produced?

Question

Quizplus · Accepted Answer

The balanced equation for the combustion of ethane is 2C2H6 + 7O2 → 4CO2 + 6H2O. The molar mass of C2H6 is 30 g/mol, so 24 g corresponds to 0.8 mol. From the equation, 2 mol of C2H6 produce 4 mol of CO2, so 0.8 mol of C2H6 will produce 1.6 mol of CO2. The molar mass of CO2 is 44 g/mol, so 1.6 mol of CO2 is 70.4 g, which is closest to 70.3 g.
