**Problem Statement:**Calculate the total concentration, in molarity, of hydroxide ions when 1,949.5 milligrams of magnesium hydroxide are completely dissolved into 0.112 L of 7.71 x 10^-1 M NaOH. Assume the added solute does not contribute significantly to the total volume. Report your answer to three significant digits.**Instructions for Students:**1. **Understand the Chemical Context:** Recognize that the problem involves the dissolution of magnesium hydroxide (Mg(OH)₂) in a sodium hydroxide (NaOH) solution.2. **Calculate the Moles of Mg(OH)₂:** - Convert 1,949.5 mg of magnesium hydroxide to grams. - Use the molar mass of Mg(OH)₂ to find the moles present.3. **Compute Moles of Hydroxide Ions from Mg(OH)₂:** - Determine the number of moles of hydroxide ions contributed by the dissolved magnesium hydroxide. (Remember that each mole of Mg(OH)₂ provides two moles of OH⁻ ions.)4. **Calculate Hydroxide Ion Contribution from NaOH:** - Use the molarity of the NaOH solution to determine moles of OH⁻ ions present in 0.112 L.5. **Determine Total Hydroxide Ion Concentration:** - Add the moles of OH⁻ ions from both sources. - Divide by the total volume to find the molarity of hydroxide ions, considering the assumption that volume addition is negligible.6. **Express Final Answer:** - Report the concentration in molarity to three significant digits.**Additional Notes:**- **Equations to Use:** - Molarity (M) = moles of solute / liters of solution - Moles = mass (g) / molar mass (g/mol)Ensure precision and use consistent units throughout calculations.

Given, mass of magnesium hydroxide [Mg(OH)2] = 1949.5 mg = (1949.5/1000) mg = 1.9495 g Concentration…
