Answer:

  • 0.4104 moles

Explanation:

The chemical reaction that yields both CO₂ and FeC₂O₄ is missing, but we can assume the following reaction:

  • Fe₂(C₂O₄)₃ → 2 CO₂ + 2 FeC₂O₄

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:

  • molar mass of CO₂: 44.01g/mol

  • number of moles = mass in grams / molar mass

  • number of moles of CO₂ = 18.06g / 44.01g/mol = 0.4104 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.
