Calculate the molarity and normality of solution containing 3.15 of hydrated oxalic acid (`{:(COOH),(|),(COOH):}.2H_(2)O`) dissolved in 250 mL of the solution.

Explanation

To calculate the molarity and normality of the solution containing 3.15 g of hydrated oxalic acid (H₂C₂O₄·2H₂O) dissolved in 250 mL of solution, we will follow these steps:

### Step 1: Calculate the molar mass of hydrated oxalic acid (H₂C₂O₄·2H₂O)

1. **Identify the components:**
- Hydrogen (H): 2 atoms
- Carbon (C): 2 atoms
- Oxygen (O): 4 atoms from oxalic acid + 2 atoms from 2 water molecules = 6 atoms total
