In the hall-heroult process, a large electric current is passed through a solution of aluminum oxide dissolved in molten cryolite , resulting in the reduction of the to pure aluminum. suppose a current of is passed through a hall-heroult cell for seconds. calculate the mass of pure aluminum produced. be sure your answer has a unit symbol and the correct number of significant digits.

Assume that a person skiing high in the mountains at an altitude of h = 15100 ft takes in the same volume of air with each breath as she does while walking at sea level. determine the ratio of the mass of oxygen inhaled for each breath at this high altitude compared to that at sea level. assume that the air composition (i. e. % of air that is oxygen) is the same at sea level as it is at 15100 ft.
