pH is simply a convenient way to denote hydrogen ion concentration (usually in moles per liter or molarity). pH is calculated from the given concentration using the equation:

pH = - log [H+].

To find [H3O+] from the given equation, we apply the antilog. 

[H+] = 10^(-pH)  or ten raised to the negative value of pH

a solution with a pH of 8.25 has a hydrogen ion concentration of 5.6234 x 10^ -9 moles per liter.

The concentration of H⁺ Ions can be calculated using following formula,

                                        pH  =  -log [H⁺]
or,
                                       -pH  =  log [H⁺]
Now, Solving for [H⁺],
                                        [H⁺]  =  10⁻⁽pH⁾
Putting value of pH,
                                        [H⁺]  =  10⁻⁽⁸·²⁵⁾

                                        [H⁺]  =  5.62 × 10⁻⁹ M
