Signs and symptoms of heat exhaustion include profuse sweating, weakness, nausea, vomiting, headache, lightheadedness, and. muscle cramps. Heat exhaustion can progress to heat stroke when the body's temperature regulation fails.
Whereas osmolality (with an â) is a measure of the osmoles (Osm) of solute per kilogram of solvent (osmol/kg or Osm/kg), osmolarity (with an r) is defined as the number of osmoles of solute per liter (L) of solution (osmol/L or Osm/L).
MOLARITY and OSMOLARITY. The concentration of a solute in a solution is expressed as its âMolarityâ. It tells you how much of a solute is present. The units of molarity are âmolesâ (mols). Osmolarity is a concept that allows you to determine if water will move from one side of a membrane to the other side.he concentration of a solute in a solution is expressed as its âMolarityâ.
