Iron is extracted from iron(III) oxide in a blast furnace. The balanced equation for the reaction is:
Fe2O3+3CO→2Fe+3CO2 \text{Fe}_2\text{O}_3 + 3\text{CO} \rightarrow 2\text{Fe} + 3\text{CO}_2 Fe2O3+3CO→2Fe+3CO2Calculate the atom economy for the production of iron in this reaction.
Give your answer to two significant figures.
(Relative formula masses: Fe2O3=160\text{Fe}_2\text{O}_3 = 160Fe2O3=160, CO=28\text{CO} = 28CO=28, Fe=56\text{Fe} = 56Fe=56, CO2=44\text{CO}_2 = 44CO2=44)
