11. For the titration of iodide ions, MnO4- ions were used, which were generated in the anode space of a coulometric cell in a sulfuric acid medium. The equivalence point was set potentiometrically. Calculate the mass (mg) of iodide in solution if the titration continued for t s at a constant current strength I mA.
Option 1
t, s 272
I, mA 18.0
