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.

Answer:

25kJ

Explanation:

Given the initial energy to be 30kJ

The energy change from the initial energy to the peak energy = (65-30) kJ

= 35kJ

since the second energy change was a drop in energy it is regarded negative

= (55-65)

= -10kJ

Therefore total energy change

= (35-10)kJ

= 25kJ
