Pleas don't provide handwritten solution ..... 

The reduction of iron(III) oxide (Fe₂O₂) 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 Fe₂O, 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. t of coke. (One metric ton, symbol 1, equals 1000 kg.)
Round your answer to 2 significant digits.
