0.13 g of Cu, when treated with `AgNO_3` solution, displaced `0.433` g of `Ag`.
`0.13` g of `AI`, when treated with `CuSO_4` solution displaced `0.47 ` g of `Cu`. 1.17 g of AI displaces `0.13` g of hydrogen from an acid. Find the equivalent weight of Ag if equivalent weights of Cu and Al are not known.

Explanation

To find the equivalent weight of silver (Ag) based on the given data, we will follow these steps:

### Step 1: Determine the equivalent weight of Aluminium (Al)
From the information provided, we know that 1.17 g of Al displaces 0.13 g of hydrogen from an acid.

The equivalent weight of hydrogen (H) is 1 g (since 1 mole of H displaces 1 mole of H2).

Using the formula for equivalent weight:
