When 8.0 g of CH₄ and 8.0 g of O₂ react, what is the maximum mass of CO₂ that could be formed?

Question

Quizplus · Accepted Answer

The balanced equation for the reaction is CH₄ + 2O₂ → CO₂ + 2H₂O. The molar mass of CH₄ is 16 g/mol, so 8.0 g of CH₄ is 0.5 mol. The molar mass of O₂ is 32 g/mol, so 8.0 g of O₂ is 0.25 mol. Since 2 moles of O₂ are required for every mole of CH₄, O₂ is the limiting reactant. 0.25 mol of O₂ will produce 0.125 mol of CO₂. The molar mass of CO₂ is 44 g/mol, so 0.125 mol of CO₂ is 5.5 g.
