My question is, would it be possible to solve this by using

My question is, would it be possible to solve this by using the pH formula and getting the concentration of the (H⁺) ions in the solution. Then take that concentration and use it in the kw formula, which then gives you the (OH^-) concentration.

If that is true, could you please work it out for me, as i think i keep getting my working out wrong somewhere?

Thank you :)
