46. To determine 8-hydroxyquinoline, the test solution was coulometrically titrated with bromine electrogenerated from KBr in the presence of H2SO4 at a constant current strength of 6.0 mA. The end of the reaction was determined biamperometrically.
Find the amount of 8-hydroxyquinoline (mg), if the electrolysis time is τ, and 4 meq of bromine is required to oxidize 1 mole of oxyquinoline:

Options a b c d e
τ, s 75.5 87 100 112 125
