A surplus of zinc is placed into $100\,\text{cm}^3$ of $1.0\,\text{mol dm}^{-3}$ hydrochloric acid. The reaction equation is given as: $\text{Zn} + \text{2HCl} \rightarrow \text{ZnCl}_2 + \text{H}_2$. Determine the greatest volume of hydrogen gas released at room temperature and pressure.
- A$1.2\,\text{dm}^3$
- B$2.0\,\text{dm}^3$
- C$2.4\,\text{dm}^3$
- D$24\,\text{dm}^3$
