A 68.4-g sample of potassium chloride was added to 200.0g of water at 20 degrees C. Is the solution saturated, unsaturated, or supersaturated?

I think you missed to add the solubility chart along with the question. I am answering the question based on my knowledge and research. The solution is basically a saturated solution. The chart actually shows the answer very clearly. I hope that you will check the cart and agree with the answer that i have provided.
