A chemistry student is given 4.00 L of a clear aqueous solution at 22.。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 22.° 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 0.56 kg. Using only the information above, can you calculate the solubility of X in water at 22.° C
If you said yes, calculate it
Be sure your answer has a unit symbol and 2 no .0 it. significant digits.
