Suppose a saturated solution of this solute was made using 85.0 g H 2 O at 20.0 °C. How much more solute can be added if the temperature is increased to 30.0 ∘ C?

This is an incomplete question, here is a complete question.

Here are the solubilities of a particular solute of two different temperatures:

Temperature (°C)         Solubility (g/100 g H₂O)

20.0                                               28.4

30.0                                               76.5

Suppose that you have made a saturated solution of this solute using 85.0 g of water at 20.0 °C. How much more solute can you add if the temperature is increased to 30.0 °C. (PLEASE explain in detail & answer in grams)

Answer : The more amount of solute added can be, 40.885 grams.

Explanation :

First we have to calculate the amount of solute at 20.0 °C.

As, 100 g of water contains amount of solute = 28.4 g

So, 85.0 g of water contains amount of solute =

Now we have to calculate the amount of solute at 30.0 °C.

As, 100 g of water contains amount of solute = 76.5 g

So, 85.0 g of water contains amount of solute =

Now we have to calculate the more amount of solute can be added.

Amount of solute added = 65.025 g - 24.14 g

Amount of solute added = 40.885 g

Thus, the more amount of solute added can be, 40.885 grams.
