Question
What is the percentage concentration of glycerin required to make an isotonic solution?
Step 1
For example, if you want to make an isotonic solution with a physiological saline solution (0.9% NaCl), the osmolarity would be around 300 mOsm/L. Show more…

What is the percentage concentration of ephedrine $\mathrm{HCl}$ required to make an isotonic solution?
1. How would you make a 30% (w/v) solution of glycerol? 2. What would the molarity of the above solution be? (The chemical formula for glycerol is C3H8O3.) 3. What is the osmolarity of the above solution? 4. What is the osmolarity of a 20% NaCl solution? 5. Assuming that these solutes are impermeant, is the 30% solution of glycerol hypertonic, hypotonic, or isotonic to the 20% solution of NaCl?
