Which relations between equivalent weight (E) and Molecular weight (M)

1.	Which relations between equivalent weight (E) and Molecular weight (M) of reactant are correct for the given change?
Answer» `FeCl_(2))` into `Fe(OH)_(2),E=(M)/(2)` `Fe_(2)(SO_(4))_(3)` into `Fe^(+2),E=(M)/(2)` `FeSO_(4)` into `Fe_(2)(SO_(4))_(3),E=(M)/(2)` `K_(2)MnO_(4)` into `KMnO_(4),E=(M)/(2)` Solution :`underset("ACTS as salt")underset(darr)overset(+2)(FeCl_(2))rarroverset(+2)(Fe)(OH)_(2)` Not a REDOX reaction EQ wt if `FeCl_(2)=(M)/(2)` `overset(+3)(Fe_(2))(SO_(4))_(3)rarr""^((+2))Fe^(+2)` Eq wt of `Fe_(2)(SO_(4))_(3)=(M)/(2)`
