The answer to your question is pH = 8.5

Explanation:

Data

pH = ?

[H₃O⁺] = 3.0 x 10⁻⁹ M

Formula

pH = - log [H₃O⁺]

-Substitution

pH = - log [3.0 x 10⁻⁹]

-Simplification

pH = - (-8.523)

-Result

pH = 8.523

-Conclusion

pH of a solution with a [H₃O⁺] of 3.0 x 10⁻⁹ is 8.5, then it is an alkaline solution.
