Question

Please Help this is all the information provided for the problem and please show your work. Thank You.

In the Hall-Heroult process, a large electric current is passed through a solution of aluminum oxide (Al_20_3) dissolved in molten cryolite (Na_3AlF_6), resulting in the reduction of the Al_20_3 to pure aluminum. Suppose a current of 8000. A is passed through a Hall-Heroult cell for 56.0 seconds. Calculate the mass of pure aluminum produced. Round your answer to 3 significant digits. Also, be sure your answer contains a unit symbol.

Explanation / Answer

Al+3 +3e- ------> Al

      Z=3

     F= 96500C

    C = 8000A

    t = 56sec

W   = MCt/ZF

W   = 27*8000*56/3*96500

= 41.78g >>>>> answer
