What is there to get.
moles = grams/molar mass.
g is given to you (8200 g).
molar mass of Fe you obtain from the periodic table. Look it up. I think it's about 55 or something like that.
And you divide one number by another. Don't try to make this harder than it is. If you can divide 4/2 you can do this.
