How many moles of Fe are obtained from one mole of Fe2O3 ????

Its simple , first of all write balanced equation

\huge\pink{Balanced equation }Balancedequation

2Fe2O3 ---------> 4Fe + 3O2

This balanced equation shows that

2 moles of Fe will produce 4 moles of Fe

then .....

1 mole of Fe2O3 will produce 2 moles of Fe

2 mole Fe2O3 = 4 mole Fe

1 mole Fe2O3 = 4/2 mole of Fe

\huge\blue{1 mole Fe2O3 = 2mole of Fe }1moleFe2O3=2moleofFe
