The osmotic pressure of a 0.9 weight percent solution of sodiumchloride (NaCl) is equal to the osmotic pressure of a 5 weightpercent solution of non-dissociating molecule X. What is themolecular weight of molecule X? The molecular weight of NaCl is58.5 g/mole (assuming 100% dissociation of NaCl in solution). Thewater density is 1 g/ml.
