Question

Weight of oxygen in fe2o3 and feo in the simple ratio for the fixed amount of iron?

Answer 1

Answer:

Fe2O3 = 48g oxygen

FeO = 16g oxygen

ratio of oxygen in Fe2O3:oxygen in FeO = 3:1

Answer 2

Weight of oxygen in one mole each of Fe₂O₃  and FeO is in the simple ratio of 3 : 1

Explanation:

One mole of Fe₂O₃ means 160 gram of Fe₂O₃

In 160 gram of Fe₂O₃ , weight of Oxygen = 16 × 3 = 48

Also, one mole of FeO means 72 gram of FeO

In 72 gram of FeO, weight of Oxygen = 16

Thus, the ratio of weight of Oxygen in Fe₂O₃  and FeO

= 48/16

= 3/1

= 3 : 1
