How many moles of carbon monoxide

Question

How many moles of carbon monoxide (CO) are required to react completely with 1.75 moles of iron (III) oxide (Fe2O3)?”
a. What unit is given in thsi equation?
B.B. What quantity is asked for?

Answer 1

The balanced chemical reaction is:

Fe₂O₃ + 3 CO --> 2 Fe + 3 CO₂

This is the reaction that occurs in a blast furnace during the reduction of iron oxide in the production of steel.

 

a. What unit is given in this equation? The stated unit is a mole, which is the molecular weight in grams.
b. What quantity is asked for? How many moles of carbon monoxide.

 

The answer is that each mole of ferric oxide requires 3 moles of carbon monoxide. Therefore, 1.75moles requires 1.75 x 3 or 5.25 moles of carbon monoxide.
