Answer:
Explanation:
The chemical reaction that yields both CO₂ and FeC₂O₄ is missing, but we can assume the following reaction:
That equation shows that 2 moles of CO₂ are formed with 2 moles of FeC₂O₄. That is a 1 : 1 mole ratio.
Then, you must convert the 18.06 grams of CO₂ into moles:
You must keep four significant figures because the initial data has one significant figure.
Thus, the number of moles of both FeC₂O₄ and CO₂ is 0.4104.
