In an acidic solution, \( \mathrm{I}^{-} \)changes to \( \mathrm{I}_{2} \). How many grams of \( \mathrm{I}_{2} \) is produced if, in the same process, 1.5
\( \mathrm{P} \) \( \times 10^{22} \) electrons are used up to reduce \( \mathrm{H}_{3} \mathrm{AsO}_{4} \) to

W \( \mathrm{H}_{3} \mathrm{AsO}_{3} \) ? \( \left(\mathrm{I}=128, \mathrm{~N}_{\mathrm{A}}=6 \times 10^{23}\right) \)
(a) \( 1.6 \mathrm{~g} \)
(b) \( 6.4 \mathrm{~g} \)
(c) \( 4.8 \mathrm{~g} \)
(d) \( 3.2 \mathrm{~g} \)
