A64.4-g sample of potassium chloride was added to 200.0 g of water at 20 degrees c. is the solution saturated, unsaturated, or supersaturated?

Hey there!:

is the solution saturated  , ie :

They are the ones that have reached the exact solubility coefficient.If we mix 64.4 g of KCl at 200.0 g of water at 20 º C, we'll see that the 32.2 g will dissolve and the remainder (32.2 g) will precipitate, forming the bottom body. In this case we will then have a solution saturated with background. However, if we want only the saturated solution, simply perform a simple filtration to separate the precipitate from the saturated solution.

hope this helps!

The answer is c. 320 g
