Question
![**Problem Statement:**
The solubility of \( \text{Mg(OH)}_2 \) is measured and found to be \( 8.82 \times 10^{-3} \) g/L. Use this information to calculate a \( K_{sp} \) value for **magnesium hydroxide**.
\[ K_{sp} = \] (blank for calculation)
**Explanation:**
This problem requires the calculation of the solubility product constant (\( K_{sp} \)) for magnesium hydroxide (\( \text{Mg(OH)}_2 \)). The solubility is provided as \( 8.82 \times 10^{-3} \) grams per liter. Use this value to determine the solubility in moles per liter, and then apply the stoichiometry of the dissociation reaction to compute the \( K_{sp} \).
**Note:**
1. Convert the given solubility from grams per liter to moles per liter using the molar mass of \( \text{Mg(OH)}_2 \).
2. Write the dissociation equation:
\[ \text{Mg(OH)}_2 (s) \leftrightarrow \text{Mg}^{2+} (aq) + 2\text{OH}^- (aq) \]
3. Use the concentration of ions to calculate the \( K_{sp} \).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F50fdeb9b-6d13-4111-b2f1-f8116069811e%2F00ee299f-6513-4d49-9c34-fbaa7a32d649%2Fgfeetm_processed.png&w=3840&q=75)
