A chemistry student is given 250.0 mL of clear aqueous solution at 42 C. He is told an unknown amount of a certain compound X is dissolved in the solution. The student allows the solution to cool to 25C. At that point, the student sees that a precipitate has formed. He pours off the remaining liquid solution, throws away the precipitate and evaporates the remaining liquid solution under vacuum. More precipitate forms. The student washes, dries, and weighs the additional precipitate. It weighs 8.75 g. Using only the information above, can you calculate the solubility of X at 25C? If yes, calculate it.
