How many grams of crystals will b formed if a saturdayed potassium nitrate solution is cooled from 60 to 30?

The amount of crystals formed will depend on how much potassium nitrate was dissolved in the solution to begin with. As the solution cools from 60°C to 30°C, potassium nitrate will begin to crystallize out of the solution. The exact amount of crystals can be determined by calculating the solubility of potassium nitrate at 30°C and comparing it to the initial concentration in the solution.
