Answer: Fe2O3
Explanation:
5.60 g Iron Oxide
- 3.92 g Iron
===========
= 1.68 g Oxygen
Convert Fe and O to moles:
3.92 g Iron/55.85 = 0.0702 moles Fe
1.68 g Oxygen/16 = 0.105 moles O
The ratio of O to Fe is 1.50. There are 3/2 O for each Fe. Multiply by 2 to get whole numbers: 2Fe for every 3O: Fe2O3
