(2) 12 : 1

Explanation:

Given: The same current is passed for the same period through molten Al2(SO4)3 and aqueous AgNO3.

Find: Ratio of the weights of Ag and Al deposited at the cathode.

Solution:

Ratio of the weights of Ag and Al deposited at the cathode = Mass of Ag / mass of Al

  = Equivalent weight of Ag / Equivalent weight of Al

  = 108 / 9

  = 12 : 1

Option 2 is the answer.
