The reduction of Iron(III) oxide (Fe2O3) to pure iron during the first step of steelmaking, 2 Fe,O,(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 Fe2O3 are -425. kJ/mol and -817. kJ/mol, respectively. Calculate the minimum mass of coke needed to produce 780. t of pure iron. (One metric ton, symbol t, equals 1000 kg.) Round your answer to 2 significant digits.
