Question
To determine the difference between osmotic pressure and vapor pressure solve this two problems and make a conclusion on the difference of osmotic and vapor pressure.
1) A 1.0 grams of protein hemoglobin is dissolved in enough water to make 200 mL of solution. The osmotic pressure of the solution is measured at 25oC and found to be 1.35mmHg. What is the molecular weight of hemoglobin?
2) The vapor pressure of water at 25oC is 23.8 mmHg. 4.57g of glucose, C6H12O6, was dissolved in 25 grams of water at this temperature. What is the vapor pressure of this solution?
