This statement is incorrect because both gold and platinum's weight vary based on the amount/volume of the material. A single kilogram of gold and platinum will weigh the same; their masses are identical as they are both elements with distinct atomic masses.

Rationale: This statement is not factually accurate. Platinum is actually denser and heavier than gold on a per kilogram basis. The density of gold is 19.32 g/cm^3, while the density of platinum is 21.45 g/cm^3, making platinum the heavier metal.

Rationale: Platinum is actually denser than gold. One kilogram of platinum takes up less volume than one kilogram of gold. So on a kilogram scale, a kilogram of gold and a kilogram of platinum would weigh exactly the same, since the scale measures mass, not density.
