Each of the following solutions is separated from a solution containing pure water with a semipermeable membrane. Assuming they all have the same temperature, rank the solutions from the highest to the lowest osmotic pressure. Rank the solutions from highest to lowest osmotic pressure. To rank items as equivalent, overlap them: 5.0% KCl, 0.7% KCl, 1.5% KCl, 1.8% KCl, 8.6% KCl.
