The reduction of iron(III) oxide (Fe₂O₁) to pure iron during the first step of steelmaking. 2 Fe,0, (s) 4Fe(s) + 30, (g) is driven by the high-temperature combustion of coke, a purified form of coal: C(s) + O₂(g) → CO₂ (g) Suppose at the temperature of a blast furnace the Gibbs free energies of formation AG, of CO₂ and Fe,0, are-440, kl/mol and-840, kl/mol, respectively. Calculate the maximum mass of pure iron that can be produced by the combustion of 620. 1 of coke. (One metric ton, symbol 1, equals 1000 kg.) Round your answer to 2 significant digits. Mi
