hydroxide ion concentration using K or Kw not Ksp

At 25 degrees C, 0.212 g of barium hydroxide Ba(OH)2 (2 in lower position) is dissolved completely in sufficent water to make 0.25 litre final solution.

What is the hydroxide ion concentration(in mol per litre) in this solution?

Give the answer in scientific notation to an appropriate number of significant figures, and state the assumption you must make in order to carry out the calculation.

The answer can only show k or kw, not ksp, as I have not been taught this as of yet.
