Fe2O3(s) + 3CO(g) → 2Fe(s) + 3CO2 What mass of carbon monoxide is needed to react with 1.80g Fe2O3

Mass of carbon monoxide : 0.95 g

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 :

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

mass CO (MW =  28,01 g/mol) :

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
