A chemistry student is given 1.00 L of a clear aqueous solution at 18.0 °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 18.0 °C. The solution remains clear. He then evaporates all of the water under vacuum. A precipitate remains. The student washes, dries and weighs the precipitate. It weighs 0.24 kg. Using only the information above, can you calculate the solubility of X in water at 18.0 °C. If you said yes, calculate it. Be sure your answer has a unit symbol and 2 significant digits.

In a laboratory determination of the atomic weight of tin, a sample of tin is weighed in a crucible. nitric acid is added, and the reaction proceeds to give a hydrated tin(iv)oxide plus no2and h2o. the hydrated tin(iv)oxide is then heated strongly and reacts as follows: sno2.xh2o(s)sno2(s)+ xh2o(g)the sno2is finally cooled and weighed in the crucible. explain the effect on the calculated atomic weight of tin that would result from each of the following experimental errors: (a)considerable spattering occurs when the nitric acid is added to the tin.(b)the hydrated tin(iv)oxide is not heated sufficiently to change it completely to tin oxide.
