**Explanation:**

The exercise involves calculating the solubility of magnesium hydroxide under different conditions. In Part A, the problem focuses on calculating solubility in a solution buffered at a specific pH. In Part B, the question asks for a comparison of this solubility with the solubility in pure water. The answers need to be in two significant figures. There are options to submit answers or request answers and feedback on incorrect attempts.
