M A solution is prepared by dissulving 4.3829 g of g barium hydroxide in 500.0 mL volumetric flask and diluting it to the calibration mark. Calculate the: Ba(OH)2 i) Normality of the Ba(OH)2 solution. (0.1024)
ii) Concentration (ppm) of OH-ion in the solution. (4 marks)

did someone know how todo ques (ii). for the (i) i got 0.1024.
