In the Hall-Heroult process, a large electric current is passed through a solution of aluminum oxide Al2O3 dissolved in molten cryolite Na3AlF6 , resulting in the reduction of the Al2O3 to pure aluminum. Suppose a current of 920.A is passed through a Hall-Heroult cell for 86.0 seconds. Calculate the mass of pure aluminum produced. Be sure your answer has a unit symbol and the correct number of significant digits.
