In the standardization of \( \mathrm{Na}_{2} \mathrm{~S}_{2} \mathrm{O}_{3} \) using \( \mathrm{K}_{2} \mathrm{Cr}_{2} \mathrm{O}_{7} \) by iodometry, the equivalent weight of \( \mathrm{K}_{2} \mathrm{Cr}_{2} \mathrm{O}_{7} \) is
(A) (molecular weight) \( / 2 \)
(B) (molecular weight) \( / 6 \)
(C) (molecular weight) \( / 3 \)
(D) same as molecular weight.
