Step-by-step explanation:

The pH of a solution can you be found by using the formula

$pH = - log [ { H_3O}^(+)]$

Since we are finding the [H3O+] , substitute the value of the pH and find it's antilog

We have

$4.63 = - log[ { H_3O}^(+)] \\ [ { H_3O}^(+)] = {10}^( - 4.63) \\ \\ = 2.344 * {10}^( - 5) mol {dm}^( - 3)$

Hope this helps you
