This page is an exercise in osmotic pressure relationships. When you press "New Problem" a solute formula appears in the first cell and the next three cells will display values. Calculate the osmotic pressure in atm, enter it in the last cell and press "Check Answer." Results appear in the scoring table. Be careful about dissociating solutes. All solutions are treated as ideal. It is assumed there are not additional processes beyond the possible solute dissociation (such as weak acid/base processes). Pressing "Show Answer" will cause the correct answer to appear and you will no longer be able submit an answer for that problem.
