7.18 g iron displaces 2.04 g copper from copper sulphate solution. If the equivalent weight of copper is 31.7, calculate the equivalent weight of iron.

Explanation

To calculate the equivalent weight of iron based on the displacement of copper from copper sulfate solution, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Given Values:**
- Mass of iron (Fe) = 7.18 g
- Mass of copper (Cu) displaced = 2.04 g
- Equivalent weight of copper (Cu) = 31.7 g/equiv
