Answer:0.593 grams of cu will be deposited
Explanation:
# W = Z× (i×t)
Where,
#[ i ]=current passed
#[ t ]=timein seconds for which current is passed
[ Z ]=equivlnt wght of substance/96500
#So, now finding charge.....
Q=it......... (3A) ×10mins ×(60) =1800 C
#now, finding Z.......
[Equivalent weight / 96500]........
equi weigh= molar mass of cu / valency
=63.5/2= 31.8 grams
So, now
#Z = 31.8/96500= 0.00032
#So now final conclusion.....
W = z×it =
0.00032×1800=0.59grams
#So, 0.59 grams of copper will be deposited
