Calculate N

Question

One mol mixture of Feo and Fe₃o₄  containing equal moles of each on reaction with excess 0₂ give 'n' moles of Fe₂o_{3 . Calculate 'N'}

Answer 1

Hi,

 

First you need to write and balance the equations for each reaction:

 

FeO  +  O₂   ---->   Fe₂O₃

 

Fe₃O₄  +  O₂   --->  Fe₂O₃ 

 

 

Once the reactions are balanced, you can easily calculate the number of mols Fe₂O₃ formed form 0.50 mol FeO and 0.50 mol Fe₃O₄.  Using the balanced reactions, i calculated that a total of 1.0 mol Fe₂O₃ will form from the mixture.

 

Hope this helps.
