pH  of a solution is found by: pH = -log[H+]

pOH of a solution is found by: pOH = -log[OH-]

The relationship between pH and pOH is: pH + pOH = 14

[H+] [OH-] = 1.0 x 10-14

For solution A:

The concentration of [H+ given is 7.6x10-12M

To find pH:

pH = -log[H+]          pH = -log [7.6x10-12]          pH = 11.12
