How many grams of potassium chloride (KCl) could be dissolved in 200g of water at 80 degrees celsius?

To determine the maximum amount of potassium chloride (KCl) that can be dissolved in 200g of water at 80 degrees Celsius, we need to consult the solubility chart or data for KCl.

One way to find this information is by looking up KCl's solubility in a water-soluble compounds database or a chemical reference book. These resources provide solubility data under various conditions.

Let's assume that the solubility of KCl in water at 80 degrees Celsius is 50 grams per 100 grams of water. This means that, at this temperature, 100g of water can dissolve 50g of KCl.

To calculate the maximum grams of KCl that can be dissolved in 200g of water at 80 degrees Celsius, we can set up a proportion:

(100g of water / 50g of KCl) = (200g of water / x grams of KCl)

Cross-multiplying, we get:

100g of water * x grams of KCl = 50g of KCl * 200g of water
100x = 10,000
x = 10,000 / 100
x = 100 g

Therefore, the maximum amount of KCl that can be dissolved in 200g of water at 80 degrees Celsius is 100 grams.
