Question

A chemistry student is given 4.00 L of a clear aqueous solution at 22°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. 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 0.56 kg.

Required:
Using only the information above, Calculate the solubility of X in water at 22° C. If you said yes, calculate it Be sure your answer has a unit symbol and 2 no .0 it. significant digits.

Answer 1

The responses to the given points can be defined as follows:

Step-by-step explanation:

In point 1:

The answer is "No".

In point 2:

The mass of solute = The mass of precipitate
`= 0.56\ kg =0.56\ * 1000 = 560 \ g`

Calculating the solubility:

`= \frac{\text{mass of solute in g}}{\text{volume of solution in ml}}\\\\ = (560)/( 4000) \\\\ = 0.14 \ (g)/(ml)`
