How many grams of potassium dichromate are required to oxidise 15.2 g of `FeSO_(4)` in acidic medium?

Explanation

To find out how many grams of potassium dichromate (K₂Cr₂O₇) are required to oxidize 15.2 g of iron(II) sulfate (FeSO₄) in acidic medium, we can follow these steps:

### Step 1: Determine the molar mass of FeSO₄
The molar mass of FeSO₄ can be calculated as follows:
- Iron (Fe) = 55.85 g/mol
- Sulfur (S) = 32.07 g/mol
- Oxygen (O) = 16.00 g/mol × 4 = 64.00 g/mol
