[f = 96500 C mol -1]
a
5.36 x 10 -4 mole
b
1. 87 x 10 10 -3 mole
c
9. 35 x 10 -4 mole
d

Cu2+2e-->cu RMM of cu=64
Therefore 2faraday=64g
Meaning 2*296500c-> 64g
360c. -> xg
Cross multiply
X=64*360/2*296500
= 360/193000
= 1.87*10^-3.

n= Q/nF
no. of moles = ?
Q= 360
nF= 96500×2=193000(copper is divalent)
n= 360/193000
=0.0001865=1.87×10-⁴(ANS)

The answer is not correct I supposed. Cu^2+ +2e ->Cu
Cu= 64
1F=Cu
360=x
2*96500 =64
360 =x
cross multiply
19300x=23040
x=23040/19300
x=1.194
