Question

How many moles of aluminum oxide will be formed from 17 moles of aluminum reaction?

__Al + __ O2 — __Al2O3

Answer 1

8.5 moles of Al₂O₃ will formed

Step-by-step explanation:

Given data:

Number of moles of Al = 17 mol

Number of moles of Al₂O₃ formed = ?

Solution:

Chemical equation:

4Al + 3O₂ → 2Al₂O₃

Now we will compare the moles of Al₂O₃ with Al.

Al : Al₂O₃

4 : 2

17 : 2/4×17 = 8.5 mol

8.5 moles of Al₂O₃ will formed.
