    Organic compound → AgBr (s)

      0.5 g                    0.40 g

    Here; Moles of Br in organic compound = Moles of Br in Ag Br

    = Moles of AgBr

    =  0 . 4 0 1 8 8 m o l

    Mass of Br in organic compound =  0 . 4 1 8 8 × 8 0 g  

    %     o f     B r = 0 . 4 × 8 0 1 8 8 × 0 . 5 × 1 0 0 % = 3 4 %
