Explain osmolarity
WebExplain osmolarity and the way in which it is measured; Describe osmoregulators or osmoconformers and how these tools allow animals to adapt to different environments; … Osmotic concentration, formerly known as osmolarity, is the measure of solute concentration, defined as the number of osmoles (Osm) of solute per litre (L) of solution (osmol/L or Osm/L). The osmolarity of a solution is usually expressed as Osm/L (pronounced "osmolar"), in the same way that the molarity of a solution is expressed as "M" (pronounced "molar"). Whereas molarity measures the num…
