The reduction of iron(III) oxide () to pure iron during the first step of steelmaking, ()()() is driven by the high-temperature combustion of coke, a purified form of coal: ()()() Suppose at the temperature of a blast furnace the Gibbs free energies of formation of and are and , respectively. Calculate the maximum mass of pure iron that can be produced by the combustion of of coke. Round your answer to significant digits.

hello your question is incomplete attached below is the complete question

answer : To 2 significant digits = 5500 kg

Explanation:

Given

C(s) + O2 (g)  ----------> CO2  ( g )

mass of CO2 = 8.9 * 10^6 g

number of moles =  8.9 * 10^6 / 12  = 7.416 * 10 ^5  mol

same amount of moles is needed by O2 hence

attached below is the detailed  solution
