Answer:
Fe:O=69.955.85:30.116=1.25:1.88=1:1.5=2:3. ∴ Its empirical formula is Fe2O3.

Answer:
Thus, 100 g of iron oxide contains 69.9 g iron and 30.1 g oxygen. So, the number of moles, we will be calculating the ratio of the number of carbon atoms present in one formula unit of iron oxide comes out to be: 3:2, So, we can conclude that the empirical formula would be: $F{{e}_ {2}} {{O}_ {3}} $.
