Question

Use the table to answer the question.A saturated solution of potassium chloride is prepared in 100.0 g of water at 20°C. If the solution is heated to 50°C, how much more KCl must be added to obtain a saturated solution?

Answer 1

In this question, we have to find the equivalent amount of mass in order to make KCl soluble when the temperature increases, we know that at 20°C, we will have a total mass of 34 grams that are soluble and saturated, when the temperature goes up to 50°C, we need to add 8.6 grams in order to achieve the amount of 42.6 grams that represents that the solution is saturated
