The equation for the reaction between magnesium and dilute sulfuric acid is given below. $\text{Mg} + \text{H}_2\text{SO}_4 \rightarrow \text{MgSO}_4 + \text{H}_2$ The $M_r$ of $\text{MgSO}_4$ equals $120$. 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$120\,\text{g}$
