If the pot can contain twice as many in volume, is it twice as heavy? Suppose that I have two pots that look like similar cylinders (e.g. Mason jars). I know that one of them can contain twice as many in volume than the other. If both are empty, is the bigger one twice as heavy as the other?
Intuitively I would say that it is less than twice as heavy, but I am not sure. Mathematically, I do a cross multiplication and conclude that the bigger one is twice as heavy, but it seems wrong to me. How to solve this problem?
Note: This is for an actual real life problem. I filled up the bigger pot and sealed it but I forgot to weigh it before and now I want to know how many grams of food it contains.
EDIT: The width of the walls seem to be the same. Can we find what is the weigh of the bigger one given the weigh of the smaller one?

No, it is not twice as heavy. The weight of the pot is determined by its mass, which is proportionate to its surface, rather than its volume.
