A) 224cc
B) 112 cc
C) 56 cc
D) None of these
Correct Answer: B
Solution :
Since, \[31.75\,\,gm\] of copper is liberated by \[96500\,\,C\] of charge, therefore \[0.3175\,\,gm\] of copper will be liberated by a charge\[=\frac{96500\times 0.3175}{31.75}=965\,\,C\] Since, \[96,500C\] of charge liberates \[11.2\] litre of hydrogen, therefore \[965C\] of charge will liberate\[=\frac{11.2\times 1000\times 965}{96500}=112\,\,cc\].
