(B) In the reaction,$N_2H_4$ acts as the reductant.The oxidation state of $N$ in $N_2H_4$ is $-2$,and in $N_2$ it is $0$.The change in oxidation state per nitrogen atom is $0 - (-2) = 2$.Since there are $2$ nitrogen atoms in $N_2H_4$,the total $n$-factor is $2 	imes 2 = 4$.The molar mass of $N_2H_4$ is $2 	imes 14 + 4 	imes 1 = 32 \ g/mol$.The equivalent weight $(EW)$ is calculated as:$EW = \frac{	ext{Molar Mass}}{n	ext{-factor}} = \frac{32}{4} = 8$.

$N_2H_4 + IO_3^- + 2H^+ + Cl^- \to ICl + N_2 + 3H_2O$. What is the equivalent weight of the reductant in the above reaction?
