The equation for one of the reactions in the process of reducing iron ore to the metal is
Fe₂O,(s) + 3 CO(g) → 2 Fe(s) + 3 CO₂(g)

(a) What is the mass of iron, in grams, that can be obtained from 454 g (1.00 lb) of iron(III) oxide?

(b) What mass of CO is required to change the iron(III) oxide to iron metal?
