Step 1
The equation provided:
2 Al + 3 FeO => Al2O3 + 3 Fe (completed and balanced9
------------------
Step 2
Information provided:
1.20 moles of FeO
-------------------
Step 3
By stoichiometry, procedure:
2 Al + 3 FeO => Al2O3 + 3 Fe
2 moles Al ----------- 3 moles FeO
X ---------- 1.20 moles FeO
X = 1.20 moles FeO x 2 moles Al/3 moles FeO
X = 0.80 moles
Answer: 0.80 moles
