Problem
A dilute aqueous solution of glucose has a concentration of 0.20molL−1. Glucose does not dissociate in water, so each dissolved molecule counts as one solute particle. The solution is separated from pure water at the same temperature T=298K by a membrane that lets water through but not glucose, and the pure-water side is large enough that the water crossing does not change it. Calculate the osmotic pressure of the solution, in Pa. Take R=8.314Jmol−1K−1.
