For the reaction : 4Fe+3O2-->2Fe2O3, if 100 g of Fe are used how much Fe2O3 are produced?

I'm having such a hard time with this..It's my physics HW and I don't know how to solve this.

100 g Fe x (1 mol Fe / 55.85 g Fe) x (2 mol Fe2O3 / 4 mol Fe) x (159.69 g Fe2O3/ mol Fe2O3)=140.27 grams Fe2O3

Also, as a side note, if you were given this in your physics class, no wonder you're confused... This is unquestionably a chemistry problem, not physics!
