Assuming you mean the common aluminum, the pure aluminum metal.
Firstly, some basic parameters should be listed. For aluminum, we know it has FCC (face-centered cubic) crystal structure, its lattice parameter a=b=c=0.405nm, α=β=γ=90o, and its molar mass M=27 g/mol. The relevant data could be found in the following link:
Chemical Data - Reaxys
Now let’s start to solve this question. Considering a unit cell, as it has four equivalent aluminum atoms, the mass of it M0=276.02∗1023∗4 g. The volume of the unit cell
