In the reaction of Mohr's salt `[FeSO_4(NH_4)_2SO_4.6H_2O]` with oxalate ions in the presence of `H_2O_2` and `H^(o+)` ions, `[Fe(C_2O_4)_3]^(3-)` ion is formed. Calculate the minimum mass of Mohr's salt and `K_2C_2O_4` required to prepare 10 g of `K_3Fe(C_2O_4)_2`.

Explanation

To solve the problem, we need to determine the minimum mass of Mohr's salt and potassium oxalate (K₂C₂O₄) required to prepare 10 g of K₃Fe(C₂O₄)₂.

### Step 1: Determine the molar mass of K₃Fe(C₂O₄)₂
The molar mass of K₃Fe(C₂O₄)₂ can be calculated as follows:
- Potassium (K): 39.1 g/mol × 3 = 117.3 g/mol
- Iron (Fe): 55.8 g/mol × 1 = 55.8 g/mol
- Oxalate (C₂O₄): (12.01 g/mol × 2 + 16.00 g/mol × 4) = 88.02 g/mol × 2 = 176.04 g/mol
