Question

1.5g of solute is dissolved in 15g of water to form a saturated solution at 298K. find out the solubility of the solute at the temperature???​

Answer 1

Solubility is an important chemical property of the solute substances.

The mathematical formula to calculate the solubility of a solute substance,is ;

Amount of solute can dissolve in 100 grams of solvent.

Now, as the data mentioned in the question,

15g solvent can dissolve = 1.5 g of solute

1g solvent can dissolve = 1.5/15 g of solute

100 g solvent can dissolve = 1.5×100/15 = 10 g of solute.

So the solubility of the solute is approximately 10g. (Answer)

Answer 2

Solubility of the solute = 10 gram

Explanation:

Given:

Amount of solute = 1.5 g

Amount of water (Solvent) = 15 g

Temperature = 298 K

Find:

Solubility of the solute

Computation:

⇒ Solubility of the solute = [Amount of solute / Amount of water (Solvent)]100

⇒ Solubility of the solute = [1.5 g / 15 g]100

⇒ Solubility of the solute = [0.1 g]100

Solubility of the solute = 10 gram
