076. Solving a chemistry problem

3. For the titration of iodide ions, MnO4- ions were used, which were generated in the anode space of the coulometric cell in a sulfuric acid medium. The equivalence point was set potentiometrically. Calculate the mass (mg) of iodide in the solution if the titration lasted 308 s at a constant current of 20.0 mA.
