Comercial Electrolytic cells for producing aluminum operate at 5.0V and 100,000 A.
(a) How long does it take to produce exactly 1 metric ton (1000 kg)of aluminum?
(b) How much electrical power (in kilowatt-hours, kW*h) is used [1W= 1 J/s; 1 kW*h= 3.6*10^3 kJ]?
(c) If electricity costs 90 cents per kW*h and cell efficiancy is90%, what is the cost of producing exaclty 1 lb of aluminum?
