Final answer:
To find how many grams of KCl dissolve in 100 g of H2O at 60°C, one would need to refer to a solubility chart for that specific temperature. The solubility of salts like KCl generally increases with temperature, and detailed data is required to provide an exact answer.
Step-by-step explanation:
The question pertains to the solubility of potassium chloride (KCl) in water at 60°C. While specific data for KCl solubility at this temperature is not provided here, solubility data for salts can typically be found in a solubility chart or table in chemistry reference books or databases.
In general, the solubility of a compound like KCl increases with temperature, meaning that more KCl would dissolve in water at 60°C than at room temperature. To answer the question, one would need to refer to the appropriate solubility data for KCl at 60°C, which typically would be given in grams of KCl that can dissolve in 100 g of water at that temperature.
Without the specific solubility data for KCl at 60°C, it's not possible to provide an exact figure. However, students can often make use of a solubility chart to find the solubility value for a given temperature. For example, if a chart indicates that at 60°C, the solubility of KCl is 45 g per 100 g of water, this would be your answer.
