Find the normality of oxalic and solution containing 6.3 g of crystalline oxalic acid in 500 ml of solution. 

Explanation

To find the normality of the oxalic acid solution containing 6.3 g of crystalline oxalic acid in 500 ml of solution, we will follow these steps:

### Step 1: Determine the molecular formula of oxalic acid
The molecular formula of oxalic acid is \( \text{H}_2\text{C}_2\text{O}_4 \).

### Step 2: Calculate the molecular weight of oxalic acid
To calculate the molecular weight, we use the atomic weights:
- Hydrogen (H) = 1 g/mol
