The volume of carbon dioxide that will be produced is 191.4 g.
Calculation:
The following is the balanced equation for the given reaction:
Fe₂O₃(s) + 3CO(g) → 2Fe(s) + 3CO₂(g),
It is obvious that when 1.0 mole of Fe2O3 reacts with 3.0 mole of CO, 2.0 mole of Fe and 3.0 mole of CO2 are produced.
Hence by using cross multiplication:
If 2.0 mol of Fe was produced with → 3.0 mol of CO₂, from stoichiometry.
Then how many moles of CO₂ are produced by 2.9 mol of Fe?
To find the answer we have a formula:
∴ The no. of moles of CO₂ produced = (3.0 mol)(2.9 mol)/(2.0 mol) = 4.35 mol.
∴ The mass of CO₂ produced = no. of moles x molar mass = (4.35 mol)(44.0 g/mol) = 191.4 g.
