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(g) 2 CO (g) 1 In the second step, iron (III) Fe₂O3(s) + 3C0(g) oxide and carbon monoxide react to form iron and carbon dioxide: 2Fe(s) + - 3 CO₂ (g) 1 Suppose the yield of the first step is 77.% and the yield of the second step is 95.%. Calculate the mass of carbon required to make 6.0 kg of iron. Be sure your answer has a unit symbol, if needed, and is rounded to the correct number of significant digits.
