You start dissolving KNO3 in the water and you find that after you've dissolved about 55 g of KNO3, you can't dissolve any more; it just sinks to the bottom.
Approximately what is the temperature of the water?
Round your answer to the nearest whole number and submit the number only; no units.
So, just find 55 on the solubility side and with your finger just move to the right untill you touch the line you should get in between 46-48. I would go more for 48.
