Yes, When metal rusts, it goes through the process of oxidization. Fe becomes FeO, or was it FeO2, but the point is, the mass per compound gets heavier. Yes, rusting is a chemical oxidation reaction. The metal in this case iron is combined with oxygen creating some iron oxide such as Fe3O4. Since the molecular weight of this molecule is greater than that of the pure iron the mass of the object will have increased. The above answer is incomplete. Actually, rust is hydrated ferric oxide. The entire surface of a rusted object gets covered with hydrated iron(III) oxide in the form of brown flakes.

∙ 10y agoRust is an oxidation reaction between iron and oxygen from the atmosphere. Because the reaction adds oxygen from the atmosphere to the iron of the nail, a rusty nail will weigh more than an non-rusty one.
The primary reaction is:
4Fe + 3O2 --> 2Fe2O3

Explain why the mass of a rusted nail would be greater than the mass of the nail before it rusted Assume that all the rust is still attatched to the nail?
Rust is a compound of iron and oxygen. Therefore the mass is greater because oxygen has been added.
Why does powdered iron rust?
Powdered iron rusts more easily because the increased surface area allows for greater exposure to oxygen and moisture, which are the primary causes of rusting. The smaller particles of powdered iron have a larger surface area compared to solid iron, leading to a faster reaction with oxygen and water.
Why does a rusty nail weigh more than the original nail?
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.
Does rust increase the weight of a nail?
The rusty nail weighs more. 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.
What happens to the mass of an iron gate when it rusts?
The mass increases until the rust flakes off,which leaves less original mass. Eventually the gate will rust completely away.
When powdered iron is left exposed to air it rest Y is the mass of the rest is greater than the mass of the powdered iron?
I believe the mass is greater as rust is the combination of iron plus oxygen, similarly the smoke and ash from a fire, if collected, would weigh more than the fuel alone before it was burnt. strange but true. Ask a chemistry boffin to prove the maths.

Why would the mass of a rusted nail would be greater than the mass of the nail before?
When iron rusts, it combines with oxygen to form iron oxide (rust). You now have the original mass of iron PLUS the mass of the combined oxygen.

Compare the mass of iron and oxygen before the reaction with the mass of rust resulting from the reaction?
The mass of iron plus the mass of oxygen used in the reaction is equal to the mass of rust formed after the reaction.Iron, Fe Relative Atomic Mass = 55.85 g/molOxygen, O Ar = 16.00 g/molRust, Fe2O3 Relative Molar Mass = 2 x 55.85 + 3 x 16.00Mr = 159.7 g/molPercentage of iron by mass = (2 x 55.85)/ 159.7 x 100= 69.94%Percentage oxygen by mass in rust = 30.06%a
Why is the mass of a rusted nail greater then the mass of the nail before it rusted?
The nail is iron. Rust is a chemical reaction. 4Fe + 3O2 --> 2Fe2O3 When the nail rusts it becomes chemically bonded to oxygen. This combination is heavier than just iron. Therefore, it gains mass.
What happens to the mass of an iron gate when it rusts?
The mass increases until the rust flakes off,which leaves less original mass. Eventually the gate will rust completely away.
Would a metal object with rust on it have a greater mass than one with out rust?
Maybe. The question is ill-defined as written. If I take a metal object of known mass, and let it rust in such a way that none of the rust crumbles and falls off the object, the rusty object will indeed have a slightly greater mass than the original object did.
