Match the units to the setup below for calculation of molarity X when dissolving a liquid X (X g)(density = D g X/mL X) in a liquid Y (Y mL)(density = D g Y/mL Y). All equations are set up so that the unit on the bottom cancels with the unit on the top to its immediate left. Be sure to match any unused answers to "Unused answer".

A chemistry student adds a quantity of an unknown solid compound X to 2.00 L of distilled water at 30.° C. After 10 minutes of stirring, only a little 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 0.052 kg. Using only the information above, can you calculate the solubility of X in water at 30.° C ? If you said yes, calculate it. Be sure your answer has a unit symbol and the right number of significant digits. O yes O no 0 0x10 ロ･ロ X μ 00 3 4
