Question
**Problem Statement:**

Calculate the concentration of H\(_3\)O\(^+\) ions present in a solution of HCl that has a measured pH of 6.110.

**Solution Attempt:**

*Entered Answer:* 0.0309 M

*Result Indicator:* Incorrect (as shown by a red cross symbol)

To correctly calculate the concentration of H\(_3\)O\(^+\) ions, use the formula:

\[ \text{[H}_3\text{O}^+\text{]} = 10^{-\text{pH}} \]

For a pH of 6.110, calculate:

\[ \text{[H}_3\text{O}^+\text{]} = 10^{-6.110} \approx 7.76 \times 10^{-7} \, \text{M} \]

Therefore, the correct concentration is approximately \( 7.76 \times 10^{-7} \, \text{M} \).
