The term mole is used in chemistry to define an amount of a substance. For example, a mole of glucose, blood sugar, weighs 180.16 grams. A common concentration unit for solutions is moles of substance per liter of solution. We abbreviate this with the symbol M. For example, 0.28M glucose really means 0.28 moles of glucose per liter of solution. How many milliliters of 0.28M glucose will contain 1.9 grams of glucose?
