Both osmolarity and osmolality are defined in terms of osmoles. An osmole is a unit of measurement that describes the number of moles of a compound that contribute to the osmotic pressureof a chemical solution. The osmole is related to osmosis and is used in reference to a solution where osmotic … See more Osmolarity is defined as the number of osmoles of solute per liter (L) of a solution. It is expressed in terms of osmol/L or Osm/L. Osmolarity depends on the number of particles in a chemical solution, but not on the … See more A 1 mol/L NaCl solution has an osmolarity of 2 osmol/L.
