Reacting amount calculations
WebUse the equation below to calculate the amount in moles of oxygen molecules that reacts with 2 mol of magnesium metal. 2Mg(s) + O 2 (g) → 2MgO(s) The equation shows that 2 mol of magnesium metal ... WebOne mole of glucose reacts with 6 moles of oxygen to produce 6 moles of carbon dioxide and 6 moles of water. So when Sal finds the moles of glucose from the grams of glucose, he multiples the moles of glucose by 6 to find the moles of oxygen since they are related to each other by a 1:6 ratio in the balanced chemical equation.
