To determine the mass of KCl that can be dissolved in 200.0g of water at 15.0°C, we need to refer to the solubility chart for KCl at different temperatures.

Solubility refers to the maximum amount of solute (in this case, KCl) that can dissolve in a given amount of solvent (water) at a specific temperature. The solubility of KCl in water is generally temperature-dependent.

Without the exact solubility chart, we can make an assumption based on the general trend. As temperature increases, the solubility of most substances also increases.

1. Search for the solubility chart of KCl in water at different temperatures. Use trusted scientific sources such as chemistry textbooks, academic journals, or online databases.

2. Locate the solubility value for KCl at 15.0°C. This value will represent the maximum mass of KCl that can dissolve in a given mass of water (200.0g).

3. Once you have the solubility value in grams per gram of water (g/g), multiply it by the mass of water (200.0g). This will give you the maximum mass of KCl that can dissolve in 200.0g of water at 15.0°C.

Keep in mind that solubility charts may vary based on different sources and conditions. Thus, acquiring the specific solubility chart for KCl at 15.0°C would be the most accurate way to determine the mass of KCl that can dissolve in water.
