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 may sound similar, but they are two distinct concepts. Molarity (M) is the number of moles of solute per liter of solution. The unit of molarity is the mole (mol). Osmolarity (Osm/L) is the total concentration of all solutes in the solution. The unit of osmolarity is the osmol (osm). Osmolarity can be used to predict whether water will move from one side of a semipermeable membrane to the other.
