Calcuting osmolarity

The osmolarity of a solution may be given as the sum of (yi)(ni)(Ci), where yi is the osmotic coefficient of solute i, n is the number of particles that solute i dissociates into and Ci is the molarity of solute i.

The osmotic coefficient (yi) has a range of 0 to 1 - the osmotic coefficient will be 1 when the solute is completely dissolved and 0 when insoluble.

so the osmolarity of your solution should be

2 x 120 (NaCl) + 3 x 0.5 (CaCl2) + 2 x 2.5 (KCl) + 3 x 1 (MgCl2) + 1 x 10 (Glucose) = 259.5 mOsm/L

TheFFM,

A small correction, the osmolarity is 259.5 mOsm/L.

Cheers,

Indeed ... Good typo spot

I will correct the original reply
