when 5.60g of an iron oxide is heated with carbon …

2019-9-4 · The mass of one mole of iron is 55.8 grams. The mass of one mole of oxygen is 16 grams. For Fe, n = 3.92 ÷ 55.8. This is approximately 0.07 mole. For O, n = 1.68 ÷ 16 = 0.105. To calculate the ratio of moles of iron to moles of oxygen, divide these two numbers. Ratio = (3.92 ÷ 55.8) ÷ 0.105 . This is approximately ⅔. The empirical formula ...
