<h3><u>Answer;</u></h3>
pH = 6.12
<h3><u>Explanation</u>;</h3>
To calculate the pH of a solution, we use the equation;
pH = -log [H3O+]
Since we are given the hydronium ion (H
3
O
+
) concentration of the solution, we can plug this value into the formula.
pH = - log [ 7.6 × 10^–7 M]
= 6.12
Thus; pH = 6.12
The answer is C) Electrons are not in a fixed position.
