Answer:
2350kg of Al₂O₃
Explanation:
<u><em>Step 1 : Write the balanced chemical equation:</em></u>
4Al + 3O₂ → 2Al₂O₃
<u><em>Step 2: Find the Ratio of Al :</em></u> Al₂O₃
Al : Al₂O₃
4 : 2
2 : 1
4700: 2350
= 2350kg of Al₂O₃
9.04354 * 10^2
The “*” identifies as a multiplication sign. Hope this helps
