A) 0.3175 g
B) 3.175 g
C) 0.635 g
D) 6.35 g
Correct Answer: A
Solution :
Given \[i=2.5\,A\] \[t=6\,\min \,26\,s=6\times 60+26=386\,\,s\] No. of coulomb passed \[=i\times t\] \[=2.5\times 386\] \[=965\,\,C\] \[C{{u}^{2+}}+2e\xrightarrow{{}}Cu\] \[\therefore \] \[2\times 96500\,\,C\] charge deposits \[Cu=63.5\,g\] \[\therefore \] 965 C charge deposits \[Cu=\frac{63.5}{2\times 96500}\times 965\] \[=0.3175\,g\]
