Question: Faraday's results are shown in Table along with the known atomic weights. Use these data to deduce the number of faradays required to produce one mole of each of the elements he studied. Assume the possibility of different numbers of elementary charges on different ionic species (which Faraday apparently did not consider) and explain why a faraday of charge might not always generate a mole atomic weight (MAW). Explain each of the six results reported in the table.
