Rust is iron oxide, a molecule consisting of iron and oxygen. The mass of the iron in the rust molecules comes from the original nail, but the mass of the oxygen has come from the air. When rust forms on iron, the mass of the iron object is increased by the mass of the oxygen that has combined with some of the iron.
A rusty nail may weigh more than a new one due to the oxidation process. Rust is formed when iron reacts with oxygen, adding mass to the nail. The rust layer can make the nail heavier than when it was in its original form.
The rust that forms on the nail is actually iron oxide, which has a greater molecular weight than iron. This additional weight from the rust causes the rusty nail to weigh more than the original nail.

If you step on a rusty nail then you would have to get a tetanus shot
It weighs more because the iron reacts with oxygen in the air to form oxides which are solids which appear to grow on the iron as more oxygen comes along. I wouldn't call it conservation of mass except in the sense that no mass is destroyed or created, but that alone doesn't explain the chemical reaction.

A nail weighs about one gram. This can vary depending on the size of the nail and what the nail is made of.
Think of this: 'a rusty nail' . . 'nail' is a noun, therefore the modifier 'rusty' is an adejctive. An adverb modifies a verb: 'He walked steadily'.
Unless you see the object that caused the injury, a person would not know if it was a nail, rusty nail, or some other object. That is why tetanus shots are given.
Homogeneous
Rusty is not an adverb (a word that modifies a verb, adjective, or other adverb). Rusty is an adjective (a word that describes a noun). Example: rusty nail.
