Answer:
If the density of a big block of gold is given as 19.3 g/ml, we can assume that the density remains constant regardless of the size or shape of the object. Therefore, the density of a small piece of gold would still be 19.3 g/ml.
The density of a substance is an intrinsic property and does not change with the size or amount of the material. So, whether it is a large block or a small piece of gold, as long as it is made of the same material, the density will remain constant.
