Calculate the molarity `(M)` and normality `(N)` of a solution of oxalic acid `[(COOH)_(2) . 2H_(2) O]` containing `12.6 g` of the acid in `500 mL` of the solution.

Explanation

To calculate the molarity (M) and normality (N) of a solution of oxalic acid \((COOH)_2 \cdot 2H_2O\) containing \(12.6 \, g\) of the acid in \(500 \, mL\) of the solution, we can follow these steps:

### Step 1: Calculate the Molar Mass of Oxalic Acid
The molar mass of oxalic acid \((COOH)_2 \cdot 2H_2O\) can be calculated as follows:
- Carbon (C): \(2 \times 12 \, g/mol = 24 \, g/mol\)
- Oxygen (O): \(4 \times 16 \, g/mol = 64 \, g/mol\)
- Hydrogen (H): \(6 \times 1 \, g/mol = 6 \, g/mol\)
