TABLE 276. 



INTERNATIONAL ATOMIC WEIGHTS AND ELECTROCHEMICAL EQUIVA- 

 LENTS. 



The International Atomic Weights are quoted from the report of the International Committee 

 on Atomic Weights ("Jour. Am. Chem. Soc.," vol. 32, p. 3, 1910). 



With the exception of the value given for silver and that corresponding to valence 2 for copper, 

 the electrochemical equivalents given in this table have been calculated from the atomic weights 

 and one or two of the more common apparent valences of th substance. The value given for 

 silver is that which was adopted by the International Congress of Electricians at Chicago in 1894.
