Osmolarity and osmolality are frequently confused and incorrectly interchanged. Osmolarity refers to the number of solute particles per 1 L of solvent, whereas osmolality is the number of solute particles in 1 kg of solvent. For dilute solutions, the difference between osmolarity and osmolality is insignificant.
Why is osmolality preferred over osmolarity?
Osmolality for aqueous solutions, is a bit higher than osmolarity, because the latter includes a little more volume (due to solutes) in the denominator, thus reducing the ratio osmoles/volume (L) with respect to osmoles/mass (kg) for the same osmoles of solute.

What is the difference between molarity osmolarity and osmolality?
The term osmolarity refers to the number of particles of solute per liter of solution, whereas the term osmolality refers to the number of particles of solute per kilogram of solvent. ... The measured osmolality should not exceed the calculated osmolality by more than 10 mOsm/kg.
