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

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

Step-by-step 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 =
`(34)/(100) g`

Maximum amount of KCl dessolbved in 200 g of water :

`(34)/(100)* 200=68 g`

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