A chemistry student is given 1.00 L of a clear aqueous solution at 18.0 °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 18.0 °C. The solution remains clear. He then evaporates all of the water under vacuum. A precipitate remains. The student washes, dries and weighs the precipitate. It weighs 0.24 kg.Using only the information above, can you calculate the solubility of X in water at 18.0 °C. If you said yes, calculate it. Be sure your answer has a unit symbol and 2 significant digits.
