For ferricyanide determination by voltammetry, 20 mL of non-electroactive KCl solution is added to the cell first. Then, 0.200 mL of 10-3 M ferricyanide solution is added to the cell and the current is measured as 0.30 μA. What is the concentration of ferricyanide in the cell, which gives this current value, in molars? please explain and solve
