The mole and the Avogadro constant — practice question

$1.00\,\text{dm}^3$ of ammonia gas is made to pass over heated copper(II) oxide. $3\text{CuO(s)} + 2\text{NH}_3\text{(g)} \rightarrow 3\text{Cu(s)} + \text{N}_2\text{(g)} + 3\text{H}_2\text{O(l)}$ At the same temperature and pressure as the ammonia, what volume of nitrogen is produced?

  • A$0.25\,\text{dm}^3$
  • B$0.50\,\text{dm}^3$
  • C$1.00\,\text{dm}^3$
  • D$2.00\,\text{dm}^3$
