Options:
A) 6.4 gm
B) 12.8 gm
C) 3.2 gm

Show Answer
Answer:
Correct Answer: C
Solution:
Equivalent weight of copper $ =\frac{64}{2}=32 $
$ \frac{\text{Equivalent weight of }Cu}{\text{Equivalent weight of }Ag}=\frac{\text{Weight of }Cu\text{ deposited}}{\text{Weight of }A\text{g deposited}} $ Weight of copper deposited $ =\frac{10.8\times 32}{108}=3.2gm $
