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 6900. A is passed through a Hall-Heroult cell for 14.0 seconds. Calculate the mass of pure aluminum produced. Round your answer to 3 significant digits. Also, be sure your answer contains a unit symbol.
