What volume of decinormal \( \mathrm{K}_{2} \mathrm{Cr}_{2} \mathrm{O}_{7} \) solution
P would be needed to convert \( 1.19 \mathrm{~g} \) of tin to stannic

W chloride in acidic medium? \( \left(\mathrm{A}_{S_{n}}=119\right) \)
(1) \( 400 \mathrm{ml} \)
(2) \( 200 \mathrm{ml} \)
(3) \( 250 \mathrm{ml} \)
(4) \( 300 \mathrm{ml} \)
