A steady current of `10.0` A is maintained in a copper voltameter . Calculate the time required to deposit `2.5` g of copper . Relative atomic mass of

`because m`=Zit and `Z=(E)/(F)=(M)/(pF) therefore m=(Mit)/(pF)` where m=2.5g. `F=96500C//"mol",M=63.5,i=10A` and p=2 `therefore t=(mpF)/(Mi)=(2.5xx2xx96500)/( 63.5xx10)= 760s`
