The mass of copper deposited is 9.589 g .
Given ,
A volatile cell using Cu/Cu2+ and Sn/Sn2+ half cells is set up at standard conditions ,and each compartment has a volume of 345 ml .
current = 0.17 A
time = 48 hrs =48 (60) (60) =172800 sec
we know , I = Q/t
thus , Q ,charge= It = 0.17 (17280) =29376 C
Then ,atomic mass of copper is 63 g
And valency of Cu is 2.
Thus , the equivalent mass of copper is 63/2 = 31.5
We know , 96500 coulombs of electricity produce copper = 31.5 g
29376 C of electricity produce copper =9.589 g
Hence , 9.589 g of Copper is deposited .
