- is the concentration of osmotically active particles in a solution.

- is a colligative property that can be measured by freezing point depression.

- can be calculated using the following equation:

Osmolarity = g x C


Osmolarity = concentration of particles (osm/L)

g = number of particles in solution (osm/mol)

C = concentration (mol/L)

- Two solutions that have the same calculated osmolarity are isos-motic. If two solutions have different calculated osmolalities, the solution with the higher osmolarity is hyperosmotic and the solution with the lower osmolarity is hyposmotic.

- Sample calculation: What is the osmolarity of a 1 M NaCl solution?

Osmolarity = g x C
