Question

A) What volume of carbon dioxide (CO₂) will be produced if 2.90 moles of iron (Fe) is produced?

Answer 1

Reaction

$\boxed{Fe_2O_3 + 3CO \rightarrow 3CO_2 + 2Fe}$

By mole- mole analysis

moles of CO2 = $2.90\times\frac{3}{2}= 4.35$ moles

The volume of one mole of CO2 at STP conditions is 22.4 liters and is 24.0 liters at room temperature and pressure.

So

(24×4.35) makes

104.4 liters of CO2.
