Calculating osmolarity
WebOsmotic concentration, formerly known as osmolarity, [1] 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 … WebThe sugar in Red Bull is a mixture of glucose and sucrose (a disaccharide made up of one molecule of glucose and one molecule of fructose bonded together). The molecular weight of sucrose is 342 g. For simplicity, however we will assume here that all the sugar is in the form of glucose. The molecular weight of glucose is 180 g.
