The reduction of iron(III) oxide (Fe₂O3) to pure iron during the first step of steelmaking, 2 Fe₂O3(s) 4Fe(s) + 30₂ (g) is driven by the high-temperature combustion of coke, a purified form of coal: C(s) + O₂(g) → CO₂ (g) 1 1 Suppose at the temperature of a blast furnace the Gibbs free energies of formation AG, of CO₂ and Fe₂O, are -413. kJ/mol and -847. kJ/mol, respectively. Calculate the minimum mass of coke needed to produce 140. t of pure iron. (One metric ton, symbol t, equals 1000 kg.). Round your answer to 2 significant digits.. kg 0.9 X 5 ?
