In a saturated solution of MgF₂ at 18°C, the concentration of Mg2+is 2.10 X 10-³ M. The equilibrium is represented by the following equation: MgF2(s) Mg2+ (aq) + 2F (aq). Write the expression for the solubility-product constant, Ksp, and calculate its value at 18°C. Note: Show all calculations, follow the rules of significant figures, and box your final answer.
