Aluminium oxide may be electrolysed at 1000°C to furnish aluminium metal (atomic mass-27 u; 1F -96500 C). The cathode reaction is Al+3e>Al To prepare 5.12 køg of aluminium metal by this method would require (b) 5.49 x 10 Cofelectricity (a) 5.49x 10' Cofelectricity (c) 1.83 x 10 Cofelectricity (d) 5.49 x 10" Cofelectricityy The one which decreases with dilution is
