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) :

the answer is d. 74.02

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2
