Consider two solutions of a nonelectrolyte separated by a semipermeable membrane that will allow passage of water, but not the nonelectrolyte. The molarity of the more concentrated solution is 0.725 M and the molarity of the less concentrated is 0.550 M. What is the minumum pressure that must be applied to stop the osmosis at 25.0 ºC? R = 0.082057 atm L mol–1 K–1
