A chemistry student is given 2.00 L of a clear aqueous solution at 42. 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 22.° 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 0.400 kg. Using only the information above, can you calculate O yes the solubility of Xin water at 22. C? O no If you said yes, calculate it. Be sure your answer has a unit symbol and the right number of significant digits.

A chemistry student weighs out 0.084 of an unknown solid compound X and adds it to 350. mL of distilled water at 23. 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 0.042 kg. Using only the information above, can you calculate the solubility of Xin water at 23.° C ? If you said yes, calculate it. Be sure your answer has a unit symbol and the right number of significant digits. 0 yes no x10 ロ・ロ X 00
A chemistry student is given 250. mL of a clear aqueous solution at 44.° 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 28.° C. At that point, the student sees that a precipitate has formed. He transfers the liquid to a clean new beaker and throws away the precipitate. The student then evaporates the water from the liquid in the new beaker under vacuum. It weighs 2.0 g. Using only the information above, can you calculate the solubility of Xin water at 28.° C ? If you said yes, calculate it. Be sure your answer has a unit symbol and the right number of significant digits.

During the cooling of the aqueous KNO3 solution, you will be asked to record the temperature when crystals first appear. What is the condition of the solution when you first noted the crystal formation?
A common practice in cooing is the addition of salt to boiling water. The boiling point of elevation is described by the equation, which is similar to freezing point depression equation but uses a different constant. imagine that your friend tells you that this is done in order to raise the temperature of the boiling water. If 1.50 kg (1.50L) of water is boiling at 100 degrees celsius how much NaCl (molar mass= 58.44g/mole) would need to be added to the water to increase the boiling point by 1 degree Celsius? Does your friend's explanation make sense?
