Mention the value of osmolarity in the interstitium- in cortex and outer medulla

Dear student,
Please find below the answer:

Osmolarity is a unit that 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. 

The osmolarity of the interstitium in the medulla of the kidney is approximately 1200 to 1400 mOsm/L. It is about 300 mOsm/L in the cortex region.

Hope this clears your doubt.
Regards.
