This is a really difficult question to answer... 1. There is no such thing as a MgO solution. Magnesium oxide reacts vigorously with water to form Mg(OH)2. 2. Mg(OH)2 is insoluble, with a Ksp of 5.61x10-12. So it doesn't form a solution with water either, it forms a suspension. Ever heard of Milk of Magnesia? That thick white liquid is a suspension of magnesium hydroxide in water. 3. Is the question asking for a concentration or the actual number of ions? The former is answerable using the Ksp. The latter is not because you would need to not only calculate the concentration, but also know the volume of the solution. So depending on what you are looking for, repost your question and I will take a shot at it.
