If 18.06 grams of CO2 are produced how many moles of FeC2O4 will also be produced

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.

i think it is d. e because the next one is igneous.
