What weighs more a pound of feathers, a pound of lead, a pound of iron or a pound of steel. Of course, they all weigh the same as they are all a pound.
The chemical compound of rust is ferric oxide so here you have two elements combined to form the rust while iron is just a single element of ferrous.
Rusting is a corrosive process usually of steel which has in it a considerable amount of iron. Suppose you had a steel nail that weighed one ounce and you left it exposed to the elements. What do you think would happen? Of course, it would eventually start to rust. Suppose you did nothing to stop it from continually rusting. It is likely after a certain amount of time passed the nails weight will become negligible and it will probably disappear. So as things rust they continue to get lighter. Check out the reference below:

Rust is heavier than iron because it is a compound of iron and oxygen. A pound of anything weighs a pound, but a pound of iron, rusted has added the weight of the oxygen.

Rust is not heavier than iron, Rust is a combination of Iron and Oxygen, Oxygen is lighter than iron so the combined mineral is less heavy than a equal volume of Iron.
But if you are thinking that a certain amount or iron gets heavier when it gets rusty, this is because the Oxygen is adding onto the iron, and making it bigger and heavier

My grandmother use to use a potato and some scouring powder, slice the end of the potato so it is flat, add the scouring powder to the pot and use the potato to scrub off, slicing bits of the potato off as needed, this should remove the rust, if not put some vinegar in the pot and scrub it then rinse well with water and wash with dish washing soap. Coat the pot with cooking oil and set in a 300 degree oven for a couple of hours to re season the pot. If things stick to the pot when you are cooking repeat the re-seasoning step....Good Luck

pure iron is just Fe. rust is iron oxide Fe2O3 use superscript. so 1 Fe is 55.85 and Fe2O3 is 55.85x2+16x3 so that is why rust is heavier.

It is? Not in my experience.
A pound of iron is heavier than a ounce of rust.
And, a box of iron is heavier than the same box full of rust.
Iron: 7.86 grams per cubic cm
Rust: 5.24 grams per cubic cm
