Calculate the osmotic pressure at 298 K of the solutions that contain: 10.5 g of MgCl_2 in 150 mL of solution. 0.650 M NaCI solution. 7.5 % glucose (non-electrolyte) by mass in water. Density of solution is 1.01 g mL^-1
What is the molar concentration (molarity) of nonelectrolyte solutes in the human body if the osmotic pressure of human blood is 7.53 atm at 37°C? R = 0.0821 (L.atm) / (mol.K) For the reaction, N2 (g) + 3 H2 (g) → 2 NH3 (g), the change in the standard free energy is – 33.32 J/mol. At 298 K, what is the value of K for this reaction?
The osmotic pressure of an aqueous solution of a certain protein was measured in order to determine the protein’s molar mass. The solution contained 3.50-g of protein dissolved in sufficient water to form 5.00-L of solution. The osmotic pressure of the solution at 25oC was found to be 1.54-mmHg. (Hint: Remember to convert mmHg to atm) Calculate the molar mass of the protein.
