10. A container is separated into two halves by a membrane. Your lab partner assistant, Thurmond, is supposed to place a MgCl2 solution on side 1 and a NaCl solution on side 2. He is then supposed to measure the rate of water movement across the membrane. Unfortunately, Thurmond is not very good about keeping complete lab notes and he has forgotten to write down some data and calculations. Using your knowledge of osmosis, complete the following table. Temperature is 15°C and the hydraulic conductivity for the membrane is 0.4 ml/atm sec. MgCl2 Concentration on Side 1 NaCl Concentration on Side 2 80 mM Osmolarity on Side 1 Osmolarity on Side 2 Difference in osmotic pressure 60 mosM across the membrane Jy 0.95 ml/sec Reflection coefficient (ơ) Direction of water movement
