At 80 degrees Celsius, the solubility of potassium chloride (KCl) in water is approximately 35.7 grams per 100 grams of water. To determine how much KCl can dissolve in 200 grams of water, we can use a simple calculation.
Since 200 grams of water is double the amount used in the standard solubility measurement (100 grams), we can simply multiply the solubility by 2. Therefore:
35.7 grams/100 grams of water × 2 = 71.4 grams of KCl
This means that at 80 degrees Celsius, you can dissolve about 71.4 grams of potassium chloride in 200 grams of water. It’s important to note that this value can vary slightly based on impurities in the water or the exact temperature, but it provides a good estimate for practical purposes.
