Numerical Problems on Colligative Properties
Q.1 Arginine vasopressin is a pituitary harmone. It helps to regulate the amount of water in the blood by reducing the flow of urine from the kidneys. An aqueous solution containing 21.6 mg of vasopressin in 100 mL of solution had an osmotic pressure of 3.70 mm Hg at 25°C. What is the molecular weight of the harmone? Q.2 The osmotic pressure of blood is 7.65 atm at 37°C. How much glucose should be used per litre for an intravenous injection that is to have the same osmotic pressure as blood. Q.3 At 300 K, 36 g of glucose present per litre in its solution has an osmotic pressure of 4.98 bar. If the osmotic pressure of solution is 1.52 bar at the same temperature, what would be its concentration? Q.4 At 20°C, the osmotic pressure of urea solution is 400 mm. The solution is diluted and the temperature is raised to 35°C, when the osmotic pressure is found to be 105.3 mm. Determine extent of dilution. Q.5 An aqueous solution of 2 per cent (wt....
