Question

Iron is obtained commercially by the reaction of hematite

(Fe2O3) with carbon monoxide. How many grams of iron is produced when 25.0 mol of hematite reacts with 30.0 mol of carbon monoxide? Fe2O3(s) + 3 CO(g) 2 Fe(s) + 3 CO2(g)

Answer 1

lAs can be seen from the chemical equation, each mole of

F

e

2

C

O

3

needs 3 moles of

C

O

. If 30 moles of

C

O

are used, only 10 moles of

F

e

2

C

O

3

can be reduced, generating 20 moles of

F

e

, corresponding to 1117 grams of iron.
