Atomic weight of barium is 137.34 The equivalent weight of barium is `BaCrO_(4)` used an an oxidising agent in acid medium is

The equivalent weights of oxidising and reducing agents can be calculated by the number of electrons gained or lost. The equivalent weight of an oxidising agent is the number of parts by weight of the substance which gains one electron. Thus, it is equal to the molecular weight of the substance divided by the number of electrons gained in the balanced chemical equation. Similarly, equivalent weight of a reducing agent is equal to the molecular weight divided by the number of electrons lost as represented in the balanced chemical equation The equivalent weight of barium in BaCrO_4 used as an oxidising agent in acidic medium is (At, wt, of Ba - 137.34)

The equivalent weight of KMnO_(4) (formula weight M) when it is used as an oxidant in neural medium is
