We need to have a balance equation:

WebThe overall chemical equation says that 1 mole of glucose reacts with 6 moles of oxygen gas for the reaction to occur. So the glucose to oxygen ratio is 1:6, or basically we need 6 times as many moles of oxygen gas as we do glucose for the reaction to happen. So 0.129 x 6 = 0.833 moles of oxygen. Hope that helps.
