1. Compute for the osmotic pressure of a 750 mL solution at 25C that contains 0.006 kg of hemoglobin (MW = 67,000 g/mol).
2. An isotonic solution yields an osmotic pressure of 5.5 atm measured against pure water at 37C. How many grams of sodium chloride must be dissolved in 850 mL of water to produce an isotonic solution?
3. The osmotic pressure of 0.03 kg of aspartame per liter is 1.85 mmHg at 35C. What is the molecular weight of this substance?
4. A 0.65 L aqueous solution contains 35 g of proteins. The osmotic pressure is 13.5 mmHg at 30C. What is the molar mass of this particular protein?
