3. Calculations of Solution Concentration: Grams per Liter Grams per liter Grams per liter is the ratio of mass units of solute to volume (liters) of solution

4. Calculations of Solution Concentration: Molarity Molarity Molarity is the ratio of moles of solute to liters of solution

5. Calculations of Solution Concentration: Mass Percent Mass percent Mass percent is the ratio of mass units of solute to mass units of solution, expressed as a percent

6. Calculations of Solution Concentration: Parts per Million Parts per million Parts per million is the ratio of mass units of solute to mass units of solution, multiplied by one million (10 6 )

7. A Simplifying Assumption 1 ml of water = 1 gram of water1 ml of water = 1 gram of water 1000 ml of water = 1 liter = 1000 grams1000 ml of water = 1 liter = 1000 grams Assume that solutions with water as the solvent have the density of pure water (1 mL = 1 gram)Assume that solutions with water as the solvent have the density of pure water (1 mL = 1 gram) –It’s not true, but it’s close enough –It’s not true, but it’s close enough
