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. WebOsmolality is a test that measures the concentration of all chemical particles found in the fluid part of blood. Osmolality can also be measured with a urine test.
