In an extremely accurate measurement of the Faraday constant, a pure silver anode was oxidized to Ag⁺ with a constant current of 0.203 6390 (± 0.0000004) A for 18 000.075 (± 0.010) s to give a mass loss of 4.097900 (± 0.000003) g from the anode. Given that the atomic mass of Ag is 107.8682 (± 0.0002), find the value of the Faraday constant and its uncertainty.
