A chemistry student is given 1.00 L of a clear aqueous solution at 17 degrees Celsius. He is told an unknown amount of a certain compound X is dissolved in the solution. The student allows the solution to cool to 17 degrees Celsius. 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 0.12 kg. Using only the information above, can you calculate the solubility of X in water at 17° C? If you said yes, calculate it and be sure your answer has a unit symbol and 2 significant digits.

An analysis was conducted to determine the potability of a 35.0-mg sample of tap water. The results revealed that the sample contain 1.8 x 10-3 μg of Lead (Pb). According to the Philippine National Standards of Drinking Water of 2017, the parameter for safe drinking water has a maximum allowable level (MAL) of 0.01 ppm of Lead (Pb) concentration. Determine whether the sample tap water is potable or not (through calculations), and briefly explain your answer.
Water and acetonitrile, CH3CN, are miscible (can be mixed in any proportions). However, whenwater and acetonitrile are mixed, the volumes are not additive (the total volume of the resultingsolution is not equal to the sum of the pure liquid volumes). For example, when 100.0 mL ofwater and 100.0 mL of CH3CN(l), are mixed at 20 °C, the total volume of the solution is 192.0mL,not 200.0 mL.a. Provide an explanation for this phenomenon.b. Calculate the molarity, molality and mol fraction of CH3CN in a solution preparedby mixing 100.0 mL of water and 100.0 mL of CH3CN(l) at 20 °C. The total volume of themixture is 192.0 mL and the densities of water and acetonitrile are 0.998 g/mL and 0.782g/mL, respectively, at this temperature.c. When 70.0 g H2O and 190.0 g CH3CN(l) are mixed, to resulting solution has adensity of 0.860 g/mL at 20 °C. Calculate the volumes of the pure liquid samples and thesolution, and show that the pure liquid volumes are not additive.
