![**Question: Osmolarity and Isotonic Solutions**
The osmolarity of physiological saline solution is 0.300 osmol/L.
**Problem:**
Assuming a membrane that is permeable only to water, what % (w/v) zinc bromide, \( \text{ZnBr}_2 \), solution is isotonic to physiological saline?
**Answer Box:**
\[ \_\_\_\_\_\_\ \% \ (w/v) \]
Note:
* Osmolarity refers to the concentration of osmotically active particles in solution.
* Isotonic solutions have the same osmolarity, hence no net movement of water occurs across the membrane.
To determine the correct % (w/v) for an isotonic \( \text{ZnBr}_2 \) solution, calculations based on the dissociation of zinc bromide into its respective ions and the osmotic balance need to be performed.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1a9ce581-7dc0-475d-98b0-a05b944e1333%2F499308d8-44f9-4a52-95f3-619fbf4c4df1%2Foc8brn.jpeg&w=3840&q=75)
