**Exercise: Solubility Expression Calculation**

Given the compound: \( \text{Mg}_3(\text{PO}_4)_2(s) \).

**Task:** Enter the solubility expression for magnesium phosphate.

**Solubility Product Constant (\( K_{sp} \)) Formula:**

The balanced dissolution equation for magnesium phosphate is:

\[ \text{Mg}_3(\text{PO}_4)_2(s) \rightleftharpoons 3\text{Mg}^{2+}(aq) + 2\text{PO}_4^{3-}(aq) \]

Using the stoichiometry of the equation, the expression for the solubility product constant (\( K_{sp} \)) is:

\[ K_{sp} = [\text{Mg}^{2+}]^3[\text{PO}_4^{3-}]^2 \]

**Note:** The concentrations of the ions in the expression are raised to the power of their coefficients from the balanced equation.
