Answer:
12g KCl will be crystallized
Explanation:
To solve this problem you need to know solubility of KCl in water at 20°C is 34g per 100g of water.
That means the maximum concentration of KCl you can dissolve at 20°C in 200g of water is 34g×2 = 68g of KCl
As solution containing 80g of KCl, the extra KCl will be crystallized after cooling, that is:
80g of KCl - 68g of KCl = <em>12g KCl will be crystallized</em>
