A chemistry student is given 200. mL of a clear aqueous solution st \( 44{ }^{\circ} \mathrm{C} \). He is told an unknown amount of a certain compound \( X \) is cissolved in the schution. The student allows the solution to cool to.27. "C. At that point, the student sees that a precipitate has formed, He transfers the squid to a clean eew beaker and throws away the precipitate. The student then evaporates the water from the liguld in the new beaker veder vacuum. It weighs \( 9.2 \mathrm{~g} \) -
