By Gabi Slizewska
A has one side with 25 ml of solvent and 3 solute molecules and one side with 75 ml of solvent and 3 solute molecules. B has one side with 50 ml of solvent and 3 solute molecules and one side with 50 ml solvent and 2 solute molecules. C has one side with 50 ml solvent and 5 molecules of solute and one side with 50 ml solvent and 10 molecules of solute. D has one side with 75 ml solvent and 9 molecules of solute and one side with 25 ml solvent and 3 molecules of solute.
