2 Al2O3 + 3C = 4Al + 3 CO2 ↑ (electrorefining) a. Calculate the Molecular Weight of Al,O3 , C, Al and CO, in reaction above Molecular weight of Al, C and O are 27, 12 and 16, respectively b. If you want to manufacture 1000 kg (1 ton) of pure Al in reaction 4, calculate the total pure alumina (Al2O3) required from reaction 4 c. If typical bauxite (alumina ore) contains 40% of alumina, calculate total bauxite have to be mined to produce 1 ton of pure Aluminum.
