Isotonic solution with physiological saline...

Postby scholesmu » Thu Aug 18, 2011 3:05 pm

an isotonic solution contains 300 mmol/L


if i need to know the molar concentration of

for example NaCl, glucose

to prepare Isotonic solution with physiological saline


is that like to have to count the total number of molecules first?
what to do?

you have to know the normality, equivalent weight and molecular mass of the isotonic solution.

of what? 300 mM NaCl will have other osmolarity than 300 mM MgSO4 ;)

Cis or trans? That's what matters.
