Question

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

Answer 1

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
