Iron ore (Fe2O2) is refined to iron (and carbon monoxide) by reacting the iron ore together...HELP!?

Iron ore (Fe2O2) is refined to iron (and carbon monoxide) by reacting the iron ore together with coke (pure carbon, C) What mass of coke is required for every 1.000 kg iron ore refined?

Steps please.
Thanks.

Answer:
The Five Steps to Stochiometry Success:


1. Balance the equation: Fe2O2 + 2 C ----> 2 CO + 2 Fe

2. Convert the given quantity to moles:

1000 g/143.6 g/mol = 6.96 mol Fe2O2


3. Find the mole ratio between given and required entities from
the balanced equation:

Fe2O2 : C
1 : 2


4. Use the mole ratio to find required moles:

Fe2O2 : C
1 : 2
6.96 mol : 13.93 mol


5. Convert required moles to requested quantity

13.93 mol x 12.0 g/mol = 167.1 g



These steps will get you through pretty much any stoichiometry question.
