Magnesium reacts with dilute sulfuric acid: $\text{Mg}(s) + \text{H}_2\text{SO}_4(aq) \rightarrow \text{MgSO}_4(aq) + \text{H}_2(g)$. At $25\,^{\circ}\text{C}$, two experiments are completed. In Experiment 1, $24.0\,\text{g}$ of powdered magnesium is reacted with $100\,\text{cm}^3$ of $1.0\,\text{mol dm}^{-3}$ sulfuric acid. In Experiment 2, $24.0\,\text{g}$ of powdered magnesium is reacted with $50\,\text{cm}^3$ of $2.0\,\text{mol dm}^{-3}$ sulfuric acid. For each experiment, the volume of hydrogen produced is recorded. The findings are shown on a graph. Which graph is the correct one?
