Ampere Atomic weights

Nevertheless, much confusion still remained. For example, very few chemists accepted the EVEN hypothesis as first announced by Avogadro and Ampere. Dumas, one of the few who did, lost his nerve when he ran across elements that yielded what seemed to be highly anomalous atomic weights.The problems would be resolved only when Cannizzaro (figure 2.6) insisted on the correctness of Avogadro s hypothesis and elaborated a method that finally gave a set of correct and consistent atomic weights. It is to Cannizzaro s work that we turn our attention to in the next chapter. 

It is not difficult to make calculations involving weights of chemical substances and the amount of electricity passing through an electrolytic cell, if you keep clearly in mind what the relation between the number of atoms and the number of electrons is. You must remember that the current of electricity, measured in amperes, is the rorte at which electricity is flowing through the cell. To find the amount of electricity the current must be multiplied by the time measured in seconds. One ampere flowing for one second is the quantity 1 coulomb of electricity. 

The theoretical capacity of a cell is determined by the amount of active materials in the cell. It is expressed as the total quantity of electricity involved in the electrochemical reaction and is defined in terms of coulombs or ampere-hours. The ampere-hour capacity of a battery is directly associated with the quantity of electricity obtained from the active materials. Theoretically 1 gram-equivalent weight of material will deliver 96,487 C or 26.8 Ah. (A gram-equivalent weight is the atomic or molecular weight of the active material in grams divided by the number of electrons involved in the reaction.)...
