Your reaction will form 132 g of iron (II) oxide.
Start by writing the balanced chemical equation for your reaction
Notice that you have a
Since you know that iron is in excess, you can safely assume that all the available oxygen will indeed react to form the oxide.
Use oxygen gas' molar mass to determine how many moles reacted
This means that the reaction produced
Now all you have to do is use iron (II) oxide's molar mass to determine how many grams would contain this many moles.
Rounded to three sig figs, the number of sig figs you gave for the mass of oxygen gas, the answer will be
