In-class Exercise 1: Osmotic Pressure Consider a solution of glucose on one side of a membrane that is impermeable to the transport of glucose. The temperature of the glucose solution is 20°C. What is the osmotic pressure on the glucose side of the membrane to stop the flow of water into the glucose solution? Assume the glucose concentration is 1 mg/ mL and that the molecular weight of glucose is 180 g/mol. What would the osmotic pressure be if the solution also contained 0.1 mg/ml of sodium chloride?

You are working as an intern in a biochemistry lab. Your advisor just isolated an enzyme and asks you to determine its molar mass using osmosis. You dissolve 1.5 g of the enzyme in water to make 500 mL of solution. You measure the osmotic pressure and find it to be 5.5 torr at 298 K. You report that the molar mass is ________ g/mol. 1 atm = 760 torr, gas constant, R = 0.08206 atm.L/mol.K.
