WebSep 5, 2013 · The difference between molality and osmolality is the use of moles of solutes compared to osmoles of solutes respectively. Osmolarity Osmolarity is the same as osmotic concentration. This is the measurement of solute concentration of a solution. The unit of osmolarity is Osm/L. WebBlood osmolality is primarily a measure of sodium dissolved in the serum. Sodium is the major electrolyte in the blood, urine, and stool. It works with potassium, chloride, and CO2 (in the form of bicarbonate) to maintain electrical neutrality in the body and acid-base balance. Sodium comes into the body in the diet and is normally conserved or ...
