When `KIO_(3)` solution is heated with excess of oxalic acid it is found that 1.683 g of `KIO_(3)` is consumed per gram of iodine liberated. Formulate the stoichemistry of the products. (Atmic weight of iodine`=127 and K=-39`)

Explanation

To solve the problem, we need to analyze the reaction between potassium iodate (KIO₃) and oxalic acid (H₂C₂O₄) and determine the stoichiometry of the products formed, specifically focusing on the amount of KIO₃ consumed per gram of iodine (I₂) liberated.

### Step-by-Step Solution:

1. **Write the Balanced Chemical Equation:**
The reaction between potassium iodate and oxalic acid can be represented as follows:
\[
2 \text{KIO}_3 + 6 \text{H}_2\text{C}_2\text{O}_4 \rightarrow \text{K}_2\text{C}_2\text{O}_4 + \text{I}_2 + 6 \text{H}_2\text{O} + 10 \text{CO}_2
