You are asked to make some calculations on a double displacement reaction between Calcium Sulfide and Potassium Chloride. If you are given 800 ml of a 1.5 M solution of Potassium Chloride and mix it with 50.2 grams of Calcium Sulfide, what is your percent yield if you formed 11.2 grams of Potassium Chloride?
