The equation showing the reaction of magnesium with dilute sulfuric acid is given below. The $M_r$ value for $\text{MgSO}_4$ is $120$. $\text{Mg} + \text{H}_2\text{SO}_4 \rightarrow \text{MgSO}_4 + \text{H}_2$ What mass of magnesium sulfate is produced when $12\,\text{g}$ of magnesium reacts completely with dilute sulfuric acid?
- A$5\,\text{g}$
- B$10\,\text{g}$
- C$60\,\text{g}$
- D$120\,\text{g}$
