Asked by Derick
Calculate the mass of Li formed by electrolysis of molten LiCl by a current of 6.7×104 A flowing for a period of 23 h . Assume the electrolytic cell is 86 % efficient.
What is the energy requirement for this electrolysis per mole of Li formed if the applied emf is + 7.3 V ?

each atom requires one electron
each electron has a charge of XXXXX columb
each ampere is a flow of one coulomb/sec
in 23 hours, yyyyy seconds have passed.
so number atoms in 23 hours must be..
Number=yyyy*current/xxxx
moles=number/avag number
energy= voltage*current/moles
