Question

Need it fast!! Given the balanced equation below, calculate the moles of aluminum that are needed to react completely with 13.2 moles of FeO?  You must show all of your work. 2Al+3FeO--> 3Fe+Al2O3

Answer 1

By looking closely into the given balanced chemical reaction, it can be deduced that the number of moles needed for every mole of FeO is only 2/3. Calculating for the number of moles of aluminum,

                      x = (13.2 moles FeO)(2 mols Al/3 moles FeO)
 
                       x = 8.8 moles Al

Answer: 8.8 moles Al
