Answer:The unknown amount of potassium chloride is 13.6 grams.Explanation:The reaction of 14 grams of KNO₃ with KCl produces a total mass of 27.6 grams of the products.

The law of conservation of mass tells us that the total mass of the reactants must be the same that the total mass of the products. So, we can find the mass of KCl as follows:

ris for reactants andpis for productsTherefore, the unknown amount of potassium chloride is 13.6 grams.I hope it helps you!
