Consider the following unbalanced reaction: Fe2O3 (s) + CO (g) --> Fe (s) + CO2 (g) How many moles of carbon dioxide are produced per mole of iron (III) oxide reacted?

1 mole, in a 1:1 ratio
You must balance the equation first.
Fe2O3(s) + 3CO(g) --> 2Fe(s) + 3CO2(g)
Now I see 3 mols CO2 per 1 mol Fe2O3.
