The useful metal manganese can be extracted from the mineral rhodochrosite by a two-step process. In the first step, manganese(II) carbonate and oxygen react to form manganese(IV) oxide and carbon dioxide: 2 MNCO(s) + 0,(g) - 2 MnO,(s) + 2 CO,(g) In the second step, manganese(IV) oxide and aluminum react to form manganese and aluminum oxidide:, 3 MnO (s) + 4 Al(s) → 3 Mn(s) + 2 Al,0,(s) Suppose the yield of the first step is 80.% and the yield of the second step is 62.%. Calculate the mass of manganese(II) carbonate required to make 9:0 kg of manganese. Be sure your answer has a unit symbol, if needed, and is rounded 5 2 significant digits.
