Ferric oxide can be obtained by oxidation of FeO:
`4FeO + O_(2) rightarrow 2Fe_(2)O_(3)`
The `O_(2)` gas required can be prepared by the following reaction.
`2SO_(3) rightarrow 2SO_(2) + O_(2)(g)`
What is the maximum amount of `Fe_(2)O_(3)` that can be produced by 144 g FeO and 160g of `SO_(3)`?
[Atomic mass of Fe = 56]
A. 320g
B. 80g
C. 120g
D. 160g
