Dear Mr. Parkhurst, Thank you very much for your fast reply. I assume you meant MolaRity is moles/L in your first sentence. Then it's completely clear to me. I forgot to take into account that molality is moles/kg total solution and not moles/kg solvent (in this case water). kind regards, eric breynaert > Molality is moles/L and the assumed density is 1.0. That implies that the > input concentrations are equal to moles/kgsolution. To convert this to > moles./kgw, the sum of the mass of the solutes is subtracted from 1 kg of > solution to obtain the number of kilograms of water. The moles divided by > the number of kilograms of water gives molality. If you increase your > concentrations, you will see more of an affect. > > David > > > > David Parkhurst (dlpark@xxxxxxxx) > U.S. Geological Survey > Box 25046, MS 413 > Denver Federal Center > Denver, CO 80225 > > Project web page: http://wwwbrr.cr.usgs.gov/projects/GWC_coupled > > > >
