A) 1930
B) 3960
C) 4825
D) 9650
Correct Answer: A
Solution :
Key Idea The quantity of electricity which can be deposited or liberated weight equal to equivalent weight is called one faraday. 1 faraday = 96500 C Atomic weight of copper = 63.4 Equivalent weight of copper \[=\frac{63.4}{2}=31.7\] \[\because \,31.7\,g\] of copper is deposited by = 96500C \[\therefore \] 1 g of copper is deposited by \[=\frac{96500}{31.7}C\] \[\therefore \] 0.634 g of copper is deposited by \[=\frac{96500}{31.7}\times 0.634=1930\,\,C\]You need to login to perform this action.
