50 grams of which solution will settle out when it is cooled from 70C to 50C [Solved]

Supposing youre looking at a solution made up of 100 g H2O:
Look at the vertical lines on the graph labeled 50 and 70 C. Then look at the curve for each salt and find the one that has a 50-gram difference between those two lines.
Only KNO3 fits the requirement, so answer 5.

settle out = come out of solution = form crystals =
stop being dissolved
