Vedclass · Answer

(B) The electrochemical equivalent $(Z)$ is related to the equivalent mass $(E)$ by the formula: $Z = \frac{E}{F}$,where $F = 96500 \ C/mol$ is Faraday's constant. Given $Z = 3.29 	imes 10^{-4} \ g/C$. $E = Z 	imes F = 3.29 	imes 10^{-4} 	imes 96500 = 31.7485 \ g/eq$. Since copper is a divalent metal $(n = 2)$,the atomic mass is given by: $	ext{Atomic mass} = n 	imes E$. $	ext{Atomic mass} = 2 	imes 31.7485 = 63.497 \ g/mol \approx 63.5 \ g/mol$.

Copper is a divalent metal. The value of its electrochemical equivalent is $3.29 \times 10^{-4} \ g/C$. Its atomic mass is (in $g/mol$)
