WebAug 13, 2024 · Osmolarity of a solution is the number of osmoles of solute per litre of solution. Osmolality is a measure of the number of particles present in solution and is independent of the size or weight of the particles. It can be measured only by use of a property of the solution that is dependent solely on the particle concentration. WebCalculate the predicted serum osmolality given the serum sodium, glucose and blood urea nitrogen. The normal range of serum osmolality is 285-295 mOsm/kg. The measured osmolality should not exceed the predicted by more than 10 mOsm/kg. A difference of more than 10 mOsm/kg is considered an osmolal gap.
