To find the solubility of KNO₃ at 20°C, we will follow these steps: ### Step 1: Determine the Mass of the Saturated Solution We know the mass of the empty dish and the mass of the dish with the solution. We can calculate the mass of the saturated solution by subtracting the mass of the empty dish from the mass of the dish and solution. \[ \text{Mass of saturated solution} = \text{Mass of dish and solution} - \text{Mass of empty dish} \] ...
