Practice objective / multiple choice question 36 from the 2023 Waec Model Questions Vol1 Biology examination.
A resting adult at sea level consumes 250 mL of O₂ per minute (measured at STP). The respiratory quotient (RQ) is 0.85. Assuming that oxidation of carbohydrate (C₆H₁₂O₆) follows the reaction C₆H₁₂O₆ + 6 O₂ → 6 CO₂ + 6 H₂O, calculate the mass of carbohydrate oxidized in one hour. (Molar volume of a gas at STP = 22.4 L; molar mass of glucose = 180 g mol⁻¹.)
