OSMOTIC COEFFICIENTS OF PHYSIOLOGICAL SOLUTES
n: number of particles
that dissociated from the solute molecule.
M.W.: Molecular Weight.
f: osmotic coefficient of
the solute
Each solution
listed contains only one type of solute and the solute concentration is the
same as what is found in the extracellular fluids of mammals - the temperature of
all the solutions is 37oC.
