A sample of magnesium hydroxide, $\text{Mg(OH)}_2$, is prepared by adding an excess of aqueous sodium hydroxide to an aqueous solution containing $1.20\,\text{g}$ of magnesium sulfate, $\text{MgSO}_4$. The mass of magnesium hydroxide obtained is $0.26\,\text{g}$. Calculate the percentage yield of magnesium hydroxide.
- A$10.5\%$
- B$21.7\%$
- C$44.8\%$
- D$61.9\%$
