### Determining the Mass of KNO₃ in a Saturated Solution at 50°CTo determine the mass of KNO₃ (potassium nitrate) in a 100 g saturated solution at 50°C, refer to the provided solubility graph. The solubility graph plots the temperature (in °C) on the x-axis and the solubility (in grams of solute per 100 grams of H₂O) on the y-axis. The graph contains solubility curves for several solutes, including KI, NH₄Cl, KNO₃, and KClO₃.#### Steps to Find the Mass of KNO₃:1. **Identify the KNO₃ curve on the graph.** This is typically marked with the chemical formula KNO₃.2. **Locate 50°C on the x-axis.** 3. **Move vertically from 50°C until you intersect the KNO₃ solubility curve.**4. **From this point of intersection, move horizontally to the y-axis to determine the solubility value.** ### Detailed Explanation of the Graph:- **X-Axis (Temperature, °C):** Spanning from 0 to 100°C.- **Y-Axis (Solubility, grams per 100 g of H₂O):** Spanning from 0 to 100 g per 100 g of water.- **Solubility Curves:** Each marked with the respective solute (KI, NH₄Cl, KNO₃, KClO₃).#### Example:For KNO₃ at 50°C:1. Locate 50°C on the x-axis.2. Follow the vertical line up to the KNO₃ curve.3. From the intersection, follow the horizontal line to the solubility value on the y-axis. 4. The value at this point is approximately 80 grams.### Conclusion:At 50°C, the solubility of KNO₃ is approximately 80 grams per 100 grams of water. Therefore, the mass of KNO₃ in a 100 g saturated solution at this temperature is 80 grams.**Calculation Prompt:**```Round to the nearest 5 grams.mass KNO₃ = [?] g```Here, you input the determined value of 80 grams, rounded as

The given graph provides us with the solubility of KNO3 in 100g of water at varying temperatures.
