#Fe_2O_3(s) + 3CO(g) rarr 2Fe(s) + 3CO_2(g)#

Approx #70*kg# of iron metal can be produced.

Explanation:

#"Moles of ferric oxide"# #=# #(100*cancel(kg)xx10^3*cancelg*cancel(kg^-1))/(159.69*cancelg*mol^-1)# #=# #626.2*mol#.

And clearly, from the stoichiometry of the reaction, #2xx626.2*cancel(mol)xx55.85*cancelg*cancel(mol^-1)xx10^-3kg*cancel(g^-1)# #=# #??#
