Based on the equation below , how many moles of carbon monoxide (CO) are needed to react completely with 1.75 moles of iron (lll) oxide (Fe2O3)

Fe2O3(s) + 3CO(g) ---2Fe(s) + 3CO2(g)

Question

Based on the equation below , how many moles of carbon monoxide  (CO) are needed to react completely with 1.75 moles of  iron (lll) oxide (Fe2O3) 

Fe2O3(s) + 3CO(g) --->2Fe(s) + 3CO2(g)

xishem · Answer

Well, we can use the factor-label system to convert from moles of iron (III) oxide to moles of carbon monoxide for this equation...$$1.75mol\ Fe_2O_3*(\frac{3mol\ CO}{1mol\ Fe_2O_3})=5.25mol\ CO$$
