A chemistry student weighs out 720. g of an unknown solid compound X and adds it to 300. mL of distilled water at 22.° C. After 10 minutes of stirring, only some of the X has dissolved. The student drains off the solution, then washes, dries and weighs the X that did not dissolve. It weighs 648. g. Using only the information above, can you calculate the solubility of X in water at 22.° C ? • yes • no If you said yes, calculate it. Be sure your answer has a unit symbol and 2 significant digits.
