Mass of carbon monoxide : 0.95 g
Further explanation
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 :
[tex]\tt \dfrac{1.8}{159.69}=0.0113[/tex]
mol ratio Fe₂O₃ : CO = 1 : 3, so mol CO :
[tex]\tt 3\times 0.0113=0.0339[/tex]
mass CO (MW = 28,01 g/mol) :
[tex]\tt m=mol\times MW\\\\m=0.0339\times 28.01\\\\m=0.950~g[/tex]
