Question

133 g of HClO2 is dissolved in 300 ml water. Then 54 g of HCl is added. (Assume no volume change.) What is the pH of the solution? What is the pOH of the solution? Is the final solution acid, basic, or neutral? SI = HOD.I- = Hd !!!

answers upside down at bottom* I just don't know how they got it
