Blast furnaces extra pure iron from the iron(III) oxide in iron ore in a two step sequence. In the first step, carbon and oxygen react to form carbon monoxide: 2C(s) + 02(8)⇒2 CO (g) In the second step, iron(III) oxide and carbon monoxide react to form iron and carbon dioxide: Fe₂O3(s) + 3CO(g)⇒ 2Fe(s) + 3 CO₂ (g) Suppose the yield of the first step is 72.% and the yield of the second step is 91.%. Calculate the mass of oxygen required to make 10.0 kg of iron. Be sure your answer has a unit symbol, if needed, and is rounded to 2 significant digits.
