![### Equilibrium Reaction of Hydrofluoric Acid
**Chemical Reaction:**
Hydrofluoric acid and water react to form fluoride anion and hydronium cation, as shown below:
\[ \text{HF} (aq) + \text{H}_2\text{O} (l) \rightarrow \text{F}^- (aq) + \text{H}_3\text{O}^+ (aq) \]
**Experimental Data:**
At a specific temperature, a chemist analyzes a reaction vessel with a volume of 7.7 L. The vessel contains an aqueous solution of hydrofluoric acid, water, fluoride anion, and hydronium cation at equilibrium, with the following composition:
| Compound | Amount (g) |
|----------|------------|
| HF | 3.21 g |
| H₂O | 600.0 g |
| F⁻ | 0.449 g |
| H₃O⁺ | 0.191 g |
**Objective:**
Calculate the value of the equilibrium constant, \( K_c \), for this reaction. Round your answer to 2 significant digits.
**Input Fields:**
A box to input the calculation of \( K_c \) is provided, with the option to use scientific notation (×10, etc.).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fabd5e741-0235-409f-80de-883f5f0e5da7%2F0c424482-c60c-4d3c-a970-ecbbd53a199d%2Fiwvn3x6_processed.jpeg&w=3840&q=75)
