hydroxide ion concentration

At 25 degrees C, 0.212 g of barium hydroxide is dissolved completely in sufficient water to make 0.25 litre of final solution. What is the hydroxide ion concentration (in mol per litre) in this solution? Answer must be in scientific notation to an appropriate number of significant figures, and state the assumption you mu ...continues
