Iron combines with oxygen and water from the air to form rust. If an iron nail were allowed to rust completely, one should find that the rust weighs:

Rust is Fe2O3.xH2O
So rust is the combined weight of the iron nail you started with PLUS the weight of the oxygen added PLUS the weight of the water added.
