Answer: A) 67.1 moles
Explanation:
The balanced reaction is :
To calculate the moles, we use the equation:
According to stoichiometry;
2 moles of iron is produced by 3 moles of carbon monoxide
89.3 moles of iron is produced by=
moles of carbon monoxide
2 moles of carbon monoxide is produced by = 1 mole of oxygen
Thus 134 moles of carbon monoxide is produced by = 
moles of oxygen
