1. a unit of measurement equal to one mole of osmotically active particles in solution
Usage: chemistry; biochemistry

Examples

• The osmolality of the solution was measured in osmoles per kilogram of water.
• Blood plasma typically contains about 0.3 osmoles of solute per liter.
• The doctor ordered tests to check the patient’s serum osmole concentration.
• Sodium chloride dissociates into two particles, so one mole produces two osmoles.
• The kidney’s ability to concentrate urine depends on osmole gradients.
• Laboratory results showed elevated osmole levels in the blood sample.
