Freezing point of ~0.5 m CaCl 2 solution Freezing point of ~1 m CaCl 2 solution WebThe difference between freezing point osmolality and vapor pressure osmolality (delta osm) is due to the presence of volatiles in the serum, because the volatiles are not measured by vapor pressure osmometry. The amount of ethanol (mg/dL) in serum is estimated by multiplying delta osm by a factor of 4.2.
