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?

A protein (P) is separated from aqueous solution as Na13P salt. A 14 ml of aqueous solution prepared by dissolving 0.300 g of this salt has an osmotic pressure of 0.48 atm at 25 °C. According to this information what is the molar mass of the protein (H13P) in kg mol? Do not write units, only enter numerical values. Use two digits at most for decimal numbers, use dot (.) as decimal separator (i.e. two-point-fifty-one should be entered as 2.51). Do not use comma () as decimal separator.
