What is osmolarity? What happens when there is high osmolarity?

Dear Student ,
Please find your answer below -

Osmolarity is a unit which is used to measure solute concentration. It is also referred as osmotic concentration. Osmolarity is measured in the terms of osmoles of solute present in one liter of solution (Osm/L). Thus, it tells about osmotic pressure contributed by number of moles of a compound of  a solution. 

Now , If the extra cellular membrane  has higher Osmolarity than the Cell , then it is said to be Hypertonic and Vice versa is known as Hypotonic Condition.

Hope this wll clear your doubts.
Regards!
