9.72 g of potassium chloride dissolves in 30 g of water at 70°C. Calculate the solubility of potassium chloride at that temperature.

Academic Chemistry NCERT Class 9

As 30 gm of water dissolves 9.72 gm of KCl.

So, the amount of KCl that gets dissolved in 100 gm of water = $\frac{9.72}{30}×100$

=32.4

Thus, the solubility of KCl at 70°C= 32.4 gm
