Answer:

Number of moles of Al₂O₃ produced = 1 mol

Explanation:

Given data:

Number of moles of Al₂O₃ produced = ?

Number of moles of Al react = 2 mol

Solution:

Chemical equation:

4Al + 3O₂     →       2Al₂O₃

Now we will compare the moles of Al and Al₂O₃.

            Al          :            Al₂O₃

             4           :              2

              2          :           2/4×2 = 1 mol

Thus, 1 mole of Al₂O₃ are produced.
