Aluminium oxide may be electrolysed at $1000^{\circ }\mathrm{C}$ to furnish aluminium metal (Atomic mass $=27$ amu; 1 Faraday $=96,500$ Coulombs). The cathode reaction is ${\mathrm{Al}}^{3+}+3{\mathrm{e}}^{-}⟶{\mathrm{Al}}^{\circ }$ To prepare $5.12\mathrm{kg}$ of aluminium metal by this method would require
