Calculate the equivalent weight of ferrous sulphate (a) as salt and (b) as reductant. 

Explanation

To calculate the equivalent weight of ferrous sulfate (FeSO4) as a salt and as a reductant, we can follow these steps:

### Step 1: Calculate the Molecular Weight of Ferrous Sulfate
The formula for ferrous sulfate is FeSO4. We need to find the molecular weight by adding the atomic weights of its constituent elements:
- Atomic weight of Iron (Fe) = 56 g/mol
- Atomic weight of Sulfur (S) = 32 g/mol
- Atomic weight of Oxygen (O) = 16 g/mol
