B)an amount greater than the sum of the masses of iron and oxygen
C)an amount less than the sum of the masses of iron and oxygen
D)There is no way to tell.
E)It depends on the reaction conditions.

The theoretical yield of FeO would be equal to the limiting reagent, which in this case is either iron or oxygen, whichever is present in lesser amount. Therefore, only a part of either iron or oxygen would be used, and the remaining amount of the other reactant would remain unreacted. Therefore, the amount of FeO produced would be less than the sum of the masses of iron and oxygen.
