thank you

10. The solubility of Cr(NO3)3-9H20 in water is 208 g per 100 g of water at 15C. A solution of Cr(NO3)3-9H2O in water of 35C is formed by dissolving 324 g in 100g of water. When this solution is slowly cooled to 15C, no precipitate forms. (a) is the solution that ha cooled down to 15C unsaturated, saturated, or supersaturated? SUPERSATURATED (b) You take a metal spatula and scratch the side of the glass vessel that contains this cooled solution, and the crystals start to appear. What has just happened? Ne) At equilibrium, what mass of crystals do you expect to form? 324-208=116 g
