A chemistry student is given 550. mL of a clear aqueous solution at 37.° 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 19.° 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 0.055 kg. Using only the information above, can you calculate the solubility of X in water at 19.° C ? If you said yes, calculate it. Be sure your answer has a unit symbol and 21 significant digits. yes no ロ・ロ X A 00 0⁰ G

A chemistry student is given 5.00 L of a clear aqueous solution at 25.° 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 15.° 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 1.00 kg. Using only the information above, can you calculate the solubility of Xin water at 15.° C ?

A salt has a solubility in water of 2.5 g/L at 25 °C Suppose you mixed 10.0g of this salt with 3.0 L of water in a beaker and allowed the salt to dissolve. The temperature of the solution was kept at 25 °C. Would there be any solid left in the beaker after the salt has dissolved? Select one: O Yes, there would be some solid would be left in the beaker. O No, there would not be any solid left in the beaker. Not enough information is provided to answer this question
A chemistry student weighs out 67.5 g of an unknown solid compound X and adds it to 3.00 L of distilled water at 17.° 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 40.5 g. Using only the information above, can you calculate the solubility of Xin water at 17.° C ? If you said yes, calculate it.

It is observed rhat 37.85 g of NaCl(MW=58.44g/mol) dissolves in 200.0 mL of water at 50 degrees Celsius. what is the molarity of NaCl in the solution. Assume that the volume of the solution does not change as the NaCL is added
The molar solubility, s, of Agl(s) in water at 25.0 °C is 9.11 x 10 mol/L. The standard enthalpy of solution, AH solution, is 110.8 kJ/mol. What is the molar solubility of Agl(s) at 71.2 °C? $71.2°C= mol/L
How is the term solubilty: Represent and quantify chemical reactions at the atomic level?
The salt cesium sulfate is soluble in water. When 22.7 g of Cs2SO4 is dissolved in 120.00 g of water, the temperature of the solution decreases from 25.00 to 22.96 °C. Based on this observation, calculate the enthalpy of dissolution of Cs2SO4 (in kJ/mol). Assume that the specific heat of the solution is 4.184 J/g °C and that the heat absorbed by the calorimeter is negligible.
