Activity 2: Effect of solute concentration on cell membranes For this activity, you will investigate what happens to red blood cells exposed to different concentrations of saline solution. Given that serum osmolarity is 0.30sm/L (serum osmolarity is nearly identical to serum osmolality), calculate the percent saline (NaCl) solution that would be isotonic. Show your work. The molar mass of NaCl is 58.44 g/mol. If you need assistance, make the following conversions: (1 point) 0.3 Osm L solution mole Osm gram mole Isotonic solution L mL Make a hypothesis about what would happen to cells exposed to a .8% (hypotonic) saline solution. (1 point) Make a hypothesis about what would happen to cells exposed to a 5% (hypertonic) saline solution. (1 point) Isotonic solution Hypertonic solution Hypotonic solution convert to % Here are images of red blood cells exposed to different concentrations of saline solutions: Hypertonic solution Hypotonic solution Fill out the following chart with your observations about cell size and shape: (1 point) Observations Activity 2: Effect of solute concentration on cell membranes For this activity, you will investigate what happens to red blood cells exposed to different concentrations of saline solution.
