EXAMPLE: What is the molarity of a solution made by dissolving 5.67 g of potassium chloride in enough water to make 100.0 mL of solution? This data gives a relationship between amount of solute and volume of solution: 5.67 g KCl / 100.0 mL. To find molarity we must convert grams KCl to moles KCl and mL solution to L: 5.67 g KCl 1 mol KCl 1000 mL 0.760 mol KCl x x = or 0.760 M KCl 100.0 mL 74.6 g KCl L L
