Fe2O3(s) + 3CO(g) → 2Fe(s) + 3CO2
Elena L [17]

Mass of carbon monoxide : 0.95 g

<h3>Further explanation</h3>

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

Reaction

Fe₂O₃(s) + 3CO(g) → 2Fe(s) + 3CO₂

MW Fe₂O₃ : 159,69 g/mol

mol Fe₂O₃ :

\tt \dfrac{1.8}{159.69}=0.0113

mol ratio Fe₂O₃ : CO = 1 : 3, so mol CO :

\tt 3\times 0.0113=0.0339

mass CO (MW =  28,01 g/mol) :

\tt m=mol\times MW\\\\m=0.0339\times 28.01\\\\m=0.950~g
