What mass of the substance T will be extracted from 150 g of the solution when we cool the solution from 50 ° C to 20 ° C?
In the table below, the solubility of the substances in water is expressed as the mass fraction of substance T in water at different temperatures.
The answer should be: 9,41 g

The mass of solid T is 7,0 g.
Explanation:
At 50 °C,
At 20 °C,
The mass of solid T is 7,0 g.
I get answer as 5.44g
Explanation:
By definition of solubility we know
"Amount of a substance (called the solute) that dissolves in 100g of a liquid substance (called the solvent) to form a saturated solution under specified conditions of temperature and pressure."
Let at
So amount of solvent in the solution
Hence by deinition of solubility
So amount of solvent in 150g solution at
On cooling to
Hence the amount of T extracted on cooling to
