Answer:
68 grams is the maximum amount of KCl that can be dissolve in 200 g of water.
Explanation:
Let the maximum amount of KCl dissolved in water be x
Solubility of KCl in water = 34g /100 g
This means that 34 g of KCl can be dissolved in 100 g of water at 20°C
Maximum amount of KCl dissolved in 1 g of water =
Maximum amount of KCl dessolbved in 200 g of water :
68 grams is the maximum amount of KCl that can be dissolve in 200 g of water.
