Explanation:
Based on the chemical equation:
4Al + 3O₂ → 2Al₂O₃
<em>4 moles of aluminium react with 3 moles of oxygen.</em>
<em />
To solve this question we need to convert the moles of aluminium to moles of oxygen using the chemical reaction:
1.875 moles Al * (3 moles O₂ / 4 moles Al) =
<h3>1.4063 moles of oxygen are required</h3>
