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
