**Question:**

What mass of aluminum oxide (101.96 g/mol) is produced by the complete reaction of 150. g of aluminum (26.98 g/mol)? Assume unlimited oxygen from air.

**Chemical Reaction:**

\[ 4 \text{Al}_{(s)} + 3 \text{O}_{2(g)} \rightarrow 2 \text{Al}_2\text{O}_{3(s)} \]

**Answer Choices:**

- ○ 375 g
- ○ 283 g
- ○ 1.13 mg
- ○ 79.4 g

**Explanation:**

The chemical equation shows that 4 moles of aluminum react with 3 moles of oxygen to produce 2 moles of aluminum oxide. Given the molar masses, calculate the mass of aluminum oxide produced from 150 grams of aluminum. Use stoichiometry to determine which answer is correct based on the balanced equation and the molar masses provided.
