how do i find the grams of potassium chloride per 100g of water in the saturated solution

I may be able to help but you must provide the solubility data.

mass of KCl 3.00g

To find the grams of potassium chloride per 100g of water in a saturated solution, you will need to know the solubility of potassium chloride in water at a given temperature. The solubility is usually expressed as grams of solute per 100 grams of water at a specific temperature.

Here are the steps to calculate the grams of potassium chloride per 100g of water in a saturated solution:

1. Determine the solubility of potassium chloride in water at the specific temperature. You can look up solubility tables or consult a reliable source such as a chemistry textbook or online database.

2. Once you have the solubility, let's call it "S," calculate the grams of potassium chloride per 100 grams of water using the following formula:

Grams of potassium chloride per 100g of water = (S/100) * 100

For example, if the solubility is 20 grams of potassium chloride per 100 grams of water, the calculation would be:

Grams of potassium chloride per 100g of water = (20/100) * 100 = 20 grams

So, in a saturated solution, you would have 20 grams of potassium chloride per 100 grams of water. Keep in mind that the solubility may vary with temperature, so ensure you have the correct solubility value for your specific conditions.
