Answer : The correct option is, (d) 68 g

Solution :

As we are given the solubility of KCl is 34 g/100 g water. Now we have to calculate the amount of KCl.

As, 100 grams of water contains 34 grams of KCl

So, 200 grams of water contains $\frac{34g}{100g}\times 200g=68g$ of KCl

Therefore, the maximum amount of KCl that can dissolve in 200 g of water is, 68 grams.

Solubility= 34.0 grams KCl/100 grams H20
200g H2O(34.0 grams KCl/100 grams H2O)
=68 g KCl
