Fluorinated organic compounds are used as herbicides, flame retardants, and fire-extinguishing agents, among other things. A reaction such as

is carried out electrochemically in liquid HF as the solvent.
(a) If you electrolyze 150 g of CH₃SO₂F, what mass of HF is required, and what mass of each product can be isolated?
(b) Is H₂ produced at the anode or the cathode of the electrolysis cell?
(c) A typical electrolysis cell operates at 8.0 V and 250 A. How many kilowatt-hours of energy does one such cell consume in 24 hours?
