**Stoichiometry Problem: Iron(III) Oxide and Carbon Monoxide Reaction**

**Question 15 of 20**

**Problem Statement:**
Consider the balanced chemical reaction below. How many grams of carbon monoxide are required to react with 6.4 g of iron(III) oxide?

\[ \text{Fe}_2\text{O}_3(s) + 3 \text{CO}(g) \rightarrow 2 \text{Fe}(s) + 3 \text{CO}_2(g) \]

**Task:**
Based on your knowledge of stoichiometry, set up the table below to determine the minimum number of moles of CO required to react with the Fe₂O₃ and then determine the amounts after the reaction goes to completion.

**Stoichiometry Table:**

|               | Fe₂O₃(s)         | 3 CO(g)        | 2 Fe(s)        | 3 CO₂(g)      |
|---------------|------------------|----------------|----------------|---------------|
| Before (mol)  |                  | 0.12           | 0              | 0             |
| Change (mol)  |                  | -0.080         | 0.080          | 0.12          |
| After (mol)   |                  | 0.040          | 0.080          | 0.12          |
