Question
In the reaction C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O, if 856 g of glucose is consumed by a person over a certain period, what is the mass of CO₂ produced?
Correct Answer
Option C is the correct answer.
Detailed Explanation
Molar mass of glucose (C₆H₁₂O₆) = 180 g/mol. Moles of glucose = 856 / 180 = 4.756 mol. From the balanced equation, 1 mol glucose produces 6 mol CO₂. Moles CO₂ = 4.756 × 6 = 28.54 mol. Mass CO₂ = 28.54 × 44 = 1255.8 g ≈ 1250 g.
Hint
Use the stoichiometric ratio from the balanced equation.
