Osmolarity, which is also known as osmotic concentration, is the measure of solute concentration. The osmolarity of a solution is usually expressed by Osm/L (pronounced "osmolar").
yes, water flows from low osmolarity to high osmolarity when two solutiona are separated by a semi-permeable membrane till the solutions on either side of the membrane attains equal osmolarity.
The osmolarity is 4 osmol/L.
The survismeter measures osmolarity by developing a standard calibration between PCI (Physicochemical indicators such as viscosity, surface tension, friccohesity) and known values of osmolarity of some molecule.
Osmolarity = Molarity x i i = number of particles produced when one formula unit of solute dissolves
The osmolarity tends to be less than 600-900 mOsm/L
It is the number of particles (ions & molecules) expressed as osmoles per litre of solution
Serum Osmolarity = 2 [Na] + [Glucose] + [BUN] (if all in mmol/L) OR Serum Osmolarity = 2 [Na] + [Glucose]/18 + [BUN]/2.8 (if glucose and BUN are in mg/dl)

Plasma Osmolarity =Total Body mOsm - Urine mOs-------------------------------------Total Body Water - Urine Volumeand: Total Body Osmolarity = PLasma Osmolarity x Weight x 0.6 Total Body Water = Weigth x 0.6
Several things affect blood osmolarity such as solute concentration, # of RBC's, albumin, salt, NaCl.
