Solution

Dear student,

For acids and bases, equivalent mass or equivalent weight is defined as the mass of an acid or base that supplies one mole H+ ions or one mole of OH- ions. The equivalent mass of an acid or base would, therefore, be given by the general equation

= Molar mass of the acid or base/ Number of H+ or OH- ions furnished by 1 mole of acid or base

For $H_{2} O_{2} i t d i s s o c i a t e s i n t o O H^{-} a n d O H^{+} i o n s .$
The equivalent weight is Molar mass of the substance divided by 1
Therefore, the equivalent weight of $H_{2} O_{2}$ is 34 g/mol

Regards
