Question

M2++2eM. 0.275g of metal M is deposited at the cathode due to passage of 1A of current for 965s. Hence the atomic weight of the metal M is :
  1. 27.5
  2. 55.0
  3. 110.0
  4. 13.75

A
27.5
B
55.0
C
110.0
D
13.75
Solution
Verified by Toppr

W=Zit0.275=at.×14×9652×96500
0.550×100=atomic weight
Hence, atomic weight= 55 g
