Question

9.72g of potassium chloride dissolve in 30g of water at 25degree c. calculate the solubility of sodium chloride in water at that temperature​

Answer 1

Solubility is given in g/100g of water; grams of solute dissolved in 100g of water.

9.72 g of potassium chloride dissolves in 30g water, then 100g of water would dissolve;

= 100/30 * 9.72

= 32.4g

Thus, the solubility of potassium chloride = 32.4g/100g of water

Answer 2

9.72g of potassium chloride dissolves in 30g water,then 100of water would dissolve.

=100/30*9.72=32.4g

then ,the solubility of potassium chloride =32.4g/100g of water
