HOW DO YOU CALCULATE OSMOLARITY?
If a
solution contains ONLY ONE type of solute (for example: ONLY glucose and
nothing else or ONLY sodium chloride and nothing else), its osmolarity can be calculated from the following equation:
osmolarity = molarity x n
n: number of particles that dissociated from the solute molecule.
If a
solution contains MANY different type of solutes (for example: BOTH glucose and
sodium chloride are in the solution), its osmolarity can
be calculated from the following equation:
osmolarity = SUM OF ALL (molarity x n) OF EACH SOLUTE
n: number of particles that dissociated from the solute molecule.
