A student dissolved 221.5 grams of cesium chloride in 100.0 grams of 90 °C water. The student then cooled that solution to 20 °C . That cooled solution formed a solid (or "precipitate"), and after separating and drying this solid the student found that the solid weighed 32.3 grams. What is the solubility of cesium chloride in water at 20 °C ? calculate your answer as grams of cesium chloride per 100 grams of water.
