Question

Calculate the weight of iron which will be converted into its
oxide ( Fe3O4) by the action of 14 4g of steam on it ?

Anita Dahiya · Accepted Answer

3Fe + 4H2O â†’ Fe3O4 + H2
3 moles of Iron react with 4 moles of steam to give 1 mole of
Fe3O4
Number of moles in14 4 grams of steam:
= 14 4 / 18
= 0 8 moles
Therefore number of moles of Fe that will react with 0 8 moles
of steam:
= 3 * 0 8 / 4
= 0 6 moles of iron will react with 0 8 moles of oxygen
1 mole of Fe weighs 56 grams
Therefore 0 6 moles will weigh:
= 56 * 0 6
= 33 6g of Fe
