AI Generated Solution

To solve the problem of calculating the solubility and \( K_{sp} \) of \( Mg(OH)_2 \) given a saturated solution with a vapor pressure of 759.5 mm at 373 K, we can follow these steps: ### Step 1: Understand the Dissociation of \( Mg(OH)_2 \) The dissociation of \( Mg(OH)_2 \) in water can be represented as: \[ Mg(OH)_2 (s) \rightleftharpoons Mg^{2+} (aq) + 2OH^{-} (aq) \] Let the solubility of \( Mg(OH)_2 \) be \( S \). Thus, at equilibrium: ...
