The mole and the Avogadro constant — practice question

The reaction equation for iron(III) oxide reacting with carbon monoxide is given below. $\text{Fe}_2\text{O}_3(s) + 3\text{CO}(g) \rightarrow 2\text{Fe}(s) + 3\text{CO}_2(g)$. Calculate the greatest mass of iron that could be produced from $480\ \text{g}$ of iron(III) oxide?

  • A$56\ \text{g}$
  • B$112\ \text{g}$
  • C$168\ \text{g}$
  • D$336\ \text{g}$
