12 Calculate the molarity and osmolarity of the following: -2.5% Dextrose (i.e., same Mw as glucose-180g: molecule does not break up, or ionize, in water) -0.33% NaCl Determining Tonicity, What makes a good I.V. solution? Normal Serum Osmolarity is approximately 0.295 Osm or 295 mOsm: Often the range of 295 to 310 solution, you'll have a good idea of whether or not it would make an appropriate intravenous drip. as a standard of comparison. Once you have calculated the osmolarity of an LV. Solution Calculations Convert the following % solutions to molarity and then calculate the osmolarity of the solution. Determine if the solution described below is an isotonic, a hypertonic, or a hypotonic solution compared to extracellular fluid (normal serum osmolarity mentioned above). 1) D5W Solution (5% Dextrose, dextrose-glucose). 2) Saline Solution ( 1.3% NaCl). 3) Normal Saline (NS) Solution (0.9% NaCl).Explanation / Answer
1. 2.5% Dextrose
2. 0.33% NaCl
3. 5% Dextrose
4. 1.3% NaCl
5. 0.9% NaCl
