The osmotic pressure Π can be calculated like this:
Π = iMRT where i is the dimensionless van 't Hoff factor M is the molarity R=0.08206 L · atm · mol-1 · K-1 is the gas constant T is the thermodynamic (absolute) temperature I have no time to do the calculation today. You may try it. should not be to hard. |
