Well you need a 1:2 molar ratio KaolIf you're using Fe2O3 which, based on a quick look at wikipedia, rust typically is.
As far as mass is concerned you want a ratio of 160:54 although that's assuming the iron oxide is dry which, if it's come from rust, it wont be.
:edit: Corrected values on account of my retarded chemical equation balancing.
