100g of a saturated solution of KNO3 was cooled from 80 degrees to 50 degrees. What mass of KNO3 would be expected to crystallise out of the solution?

Answered by DrBob222
Few people memorize solubility tables. Surely you have a graph or table giving the solubility of KNO3 vs temperature. If you will post the solubility in those tables/graph at 80 C and 50 C I can show you how to do this.

KNO3 solubility at 80 C is 180g/100g
KNO3 solubility at 50 C is 78g/100g

kCl at 40 degrees
