Achemistry student is given 600. ml of a clear aqueous solution at 37.° 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 21.° c. 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 water from the remaining liquid solution under vacuum. more precipitate forms. the student washes, dries and weighs the additional precipitate. it weighs 0.084 kg. using only the information from above, can you calculate the solubility of x at 21.° c?
