What is the total number of moles of products formed when 3 moles of Fe₃O₄ react with 8 moles of Al in the given reaction, 3Fe 3 O 4 (s) + 8 Al (s) → 9 Fe (s)+ 4Al 2 O 3 (s)?

Step-by-step solution

According to the stoichiometry of the reaction, for every 3 moles of Fe₃O₄ reacting with 8 moles of Al, you will produce 9 moles of Fe and 4 moles of Al₂O₃. Therefore, the total moles of products are 9 + 4 = 13 moles.
