In a saturated solution that is in contact with solid \( \mathrm{Mg}(\mathrm{OH}) 2 \), the concentration of \( \mathrm{OH}- \) is \( 8.1 \times 10^{-5} \mathrm{M} \). What is the solubility product for \( \mathrm{Mg}(\mathrm{OH}) 2 \) ? Please input your answer as \( \times 10^{2} \) For example, if I calculate the answer is \( 1.1 \mathrm{x} \) \( 10 \rightarrow 2(0.011) 1 \) would type in \( 1.1 \) for \( A \) and \( -2 \) for \( B \).
