- The osmolarity of body fluids is maintained at ___________ . 100 mOsm 300 mOsm 1000 mOsm it is not constantly maintainedWhat is the osmolarity of the solution? Is it hypertonic, isotonic, or hypotonic with blood plasma (0.30 osmol)? Discuss possible medicinal reasons forthe osmolarity of the solution.In an investigation of osmosis, apple cores were submerged in different molarity solutions to determine the unknown osmolarity of the apple. To determine the molarity five uniform apple cores were massed before submerging them in different molarity solutions. After 24 hours the apple cores were massed again. Then the percent change in mass was determined for the five uniform apple cores in each molarity solution. (b) Identify the osmolarity of the apple.
