Physical Properties of Solutions  Lesson Objectives Use different ways of expressing concentration of solutions: percent by mass, mole fraction, molarity, molality, percent by volume, percent by mass, ppm (STEM_GC11PPIIId-f-111) Perform stoichiometric calculations for reactions in solution (STEM_GC11PPIIId-f112);  Solution Solute Solvent A solute is defined as the A solvent is a substance that substance that is dissolved in a dissolves a solute, resulting in a solution solution  Types of Solutions Saturated Solution Unsaturated - -> contains the maximum amount -> contains less solute than it ofa solute in a given solvent has the capacity to dissolve Supersaturated -> contains more solute than is present in a saturated solution Concentration The concentration of a solution is a measure of the amount of solute that has been dissolved in a given amount of solvent or solution. Ways of Expressing Concentration Concentration Units Concentration Units  2. Calculate the mass percent of sodium iodide dissolved in each of the following solutions a) 6.5 g of NaI in 190 g of water 3. A 2.5 g sample of groundwater was found to contain 5.4 μg of Zn2+. What ids the concentration of Zn2+ in ppm? Concentration Units Concentration Units Concentration Units  Concentration Units 2. Determine the molarity of a solution containing 1.45 moles of Potassium chloride in enough water to give 875 mL of solution  Concentration Units Example: A solution is made by dissolving 4.35 g glucose (C6H12O6) in 25.0 mL of water. Calculate the molality of glucise in the solution. Density of water is 1.oo g/mL.  Concentration Units 2. Calculate the molality of a sulfuric acid solution containing 24.4 g of H2SO4 in 198 g water.
