Calculate the normality of solution containing 31.5 g of hydrated oxalic acid `(H_(2)C_(2)O_(4).2H_(2)O)` in 1250 mL of solution.

Explanation

To calculate the normality of a solution containing 31.5 g of hydrated oxalic acid \((H_2C_2O_4 \cdot 2H_2O)\) in 1250 mL of solution, follow these steps:

### Step 1: Calculate the molar mass of hydrated oxalic acid
The molar mass of hydrated oxalic acid \((H_2C_2O_4 \cdot 2H_2O)\) can be calculated as follows:

- Molar mass of \(H_2C_2O_4\):
- Hydrogen (H): \(2 \times 1.01 \, \text{g/mol} = 2.02 \, \text{g/mol}\)
- Carbon (C): \(2 \times 12.01 \, \text{g/mol} = 24.02 \, \text{g/mol}\)
