Osmolality refers to the concentration of osmotically active particles in a solution. It is a measure of the number of solute particles in a kilogram of solvent. Osmolality is typically used in medical and biological settings to assess the concentration of electrolytes, glucose, and other solutes in bodily fluids such as blood or urine. It is considered a more accurate measure of solute concentration compared to osmolarity, which measures the concentration per liter of solution. Osmolality is important for maintaining proper water balance and osmotic pressure in the body.
