Aluminum has a density of 2.7 grams per milliliter. An element in the boron group, aluminum is a very light metal, but it is dense enough to sink in water. It is the third most abundant element in the Earthâs crust and is the most abundant metal overall.
1 Answer 1. So we are assuming that Aluminium is a sphere. Notice that $Density=\frac {mass}{Volume}$. Also notice that the atomic mass given is for one mole of Aluminium. Therefore, you must convert the mass to a single atom (use mole). The Volume is $Volume=\frac{mass}{Density}$ and the Volume of a sphere is $Volume=\frac{4}{3}\pi r^3$.
