Osmolarity - (Mar/29/2007 )

Some body knows how to increase the osmolarity of extracellular solution.I know to add glucose to increase the osmlarity of solution but whats the exact formula to calulate how much amount of glucose is to add in an extracellular soultion.

---

for glucose, mosM ~ mM

for NaCl, 2 mosM ~ 1 mM

NaCl was an example for osmolarity of a full dissociating salt; the same is true of course for KCl; check osmolarity of your solution with a calibrated osmometer; even accurately prepared solutions may have some differences to estimated osmolarity
