100.00 cm3 of solution was prepared from a sample of ВаСI2*2H2O weighing 1.099 g. To 20.00 cm3 of which was added Na2MgY. 17.65 cm3 of 0.05085 M complexone III was used for titration of the resulting mixture. Calculate the mass fraction of BaCI2 in the sample, assuming that when barium is titrated in the presence of magnesium, n (Ba) = n (set III) = n (Mg).
