A chemistry student adds a quantity of an unknown solid compound X to 550. mL of distilled water at 30.° C. After 10 minutes of stirring, all of the X has dissolved. The student then drains off the solution and evaporates the water under vacuum. A precipitate is left behind. The student washes, dries and weighs the precipitate. It weighs 19.3 g. Using only the information above, can you calculate O yes the solubility of X in water at 30.° C? O no If you said yes, calculate it. Be sure your answer has a unit symbol and the right number of significant digits. olo
