Quizplus · Accepted Answer

According to the balanced chemical equation, the stoichiometric ratio between C₈H₁₈ and CO₂ is 2:16 or 1:8. Therefore, if 3.00 moles of C₈H₁₈ is completely consumed, the theoretical yield of CO₂ is 3.00 moles/2 x 16 = 24.00 moles. However, we also need to consider the amount of O₂ available. The stoichiometric ratio between O₂ and CO₂ is 25:16 or 5:4. Therefore, if 3.00 moles of O₂ is completely consumed, the limiting reagent is O₂ and the theoretical yield of CO₂ is 3.00 moles x 16/25 x 4/5 = 1.92 moles. Therefore, the best choice is C.
