if you make a solution by dissolving 1.0 mol of Fecl3 into 1 kg of water how would the osmotic pressure of this solution compare with the osmotic pressure of a solution that is made from 1.0 mol of glucose in 1 kg of water
Thus the FeCl3 will form 3 Cl- ions and 1 Fe3+ ion. So the molarity of ions of FeCl3 is 4 times than glucose. So according to the calculation formula, the osmotic of FeCl3 is 4 times of glucose.
