Question

What is the maximum amount of kcl that can dissolve in 200 g of water? (the solubility of kcl is 34 g/100 g h2o at 20°c.)?

Answer 1

The correct answer is 68 g
hope this helps!!

Answer 2

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 = $\frac{34}{100} g$

Maximum amount of KCl dessolbved in 200 g of water :

$\frac{34}{100}\times 200=68 g$

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