4Fe +302–> 2Fe2O3 how many moles of Fe2O3 are produced when 0.27 moles of Fe is reacted?

0.14 moles of Fe₂O₃

Explanation:

Given parameters:

Number of moles of Fe  = 0.27moles

Unknown:

Number of moles of Fe₂O₃ = ?

Solution:

To solve this problem, we are going to the work from the known specie to the unknown using their number of moles.

We first obtain the balanced equation of the reaction;

                 4Fe   +    3O₂     →    2Fe₂O₃

The equation above is balanced;

                    4 moles of Fe produced 2 moles of Fe₂O₃

                  0.27 moles of Fe will produce      = 0.14 moles of Fe₂O₃

c. is the answer
