What is the osmolarity of the dialysate fluid? HCO3- 35.0 mEq/L K+ 2.0 mEq/L Na+

Question

What is the osmolarity of the dialysate fluid? HCO3- 35.0 mEq/L K+ 2.0 mEq/L Na+ 130.0 mEq/L Ca2+ 6.0 mEq/L Mg2+ 3.0 mEq/L Cl- 106.0 mEq/L Glucose 5.0% (m/v) I have sent this question 2 times. Pearson said the answer is wrong. It said the dissolved glucose was not contributed towards the osmotic pressure. Thanks What is the osmolarity of the dialysate fluid?

Explanation / Answer

Osmolarity ,mosm/kg = n*meq/valency

For HCO3- osmolarity=1 *35/1 =35mosm/kg similarly find for all

For all given ions n=1 valencies k+,Na+,cl-has 1 valency

And Ca2+,Mg2+ has 2 valencies calculate and add accordingly all osmolarities

dissolved glucose not to be considered
