Final answer:
The density of Americium is inversely proportional to its volume. It is calculated by dividing the mass of the substance by its volume.
Step-by-step explanation:
The density of a substance is the mass per unit volume. It is calculated by dividing the mass of the substance by its volume. In the case of the element Americium, its density is inversely proportional to its volume.
Mathematically, this can be represented as:
p = k/v
where p is the density, k is a constant, and v is the volume of Americium.
