WebThe reaction that took place when 2 moles of NH3 were exposed to 3 moles of CuO resulted in the production of 1 mole of N2, as well as 3 moles of copper(s), and 3 moles of water. It was determined that the theoretical yield of this reaction was 17.03 g of N2 by first multiplying 9.05 g of NH3 by 1 mole of NH3, and then dividing that result by ... WebSo to determine how many moles of oxygen atoms are present in a sample of glucose, we simply need to multiple the moles of glucose by six. So if we have 0.139 mols of glucose, we will have 0.833 mols of oxygen (0.139 x 6 = 0.834, but accounting for sig figs it becomes 0.833). Hope that helps.
