The mole and the Avogadro constant — practice question

In a complete combustion reaction, a hydrocarbon forms only carbon dioxide, $\text{CO}_2$, and water, $\text{H}_2\text{O}$. $\text{C}_5\text{H}_{12}(l) + 8\text{O}_2(g) \rightarrow 5\text{CO}_2(g) + 6\text{H}_2\text{O}(g)$ If $0.1\,\text{mol}$ of the hydrocarbon $\text{C}_5\text{H}_{12}$ undergoes complete combustion, what volume of carbon dioxide is produced at room temperature and pressure?

  • A$0.5\,\text{dm}^3$
  • B$2.4\,\text{dm}^3$
  • C$5.0\,\text{dm}^3$
  • D$12\,\text{dm}^3$
