Question- You add 25.0 grams of sugar to 9.00 grams of water at 20 deg C. The you heat it to 80 deg C and add 5.00 more grams of sugar. Assuming you do not get a supersaturated solution, what is the amount of sugar in the solution and the amount of solid out of solution, if he cools it to 58 deg C?
Any help is greatly appreciated!
