Given the balanced equation below, calculate the moles of aluminum that are needed to react completely with 13.2 moles of feo? 2al + 3feo 3fe +al2o3

The number of moles of aluminium  that are needed to react completely  with 13.2 moles of FeO  is  8.8 moles

calculation

2Al + 3FeO → 3aFe +Al2O3

by use of of mole ratio of Al: FeO  from  equation above = 2:3 the moles of  Al is  therefore

= 13.2  x  2/3=8.8  moles  of Al

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
