What is the osmotic pressure of a solution at 37°C containing a solute with a molecular weight of 75,000 at a concentration of 30 g L−1 and a solute with a molecular weight of 20,000 at a concentration of 10 g L−1? The solute with a molecular weight of 75,000 is unstable in this solution and completely dissociates into four solutes of equal size.
