3. Molybdenum has a BCC crystal structure, an atomic radius of 0.1363 nm, and an atomic
weight of 95.94 g/mol. Compute its theoretical density.
10- Iron, Fe, can have two different crystal structure (BCC and FCC).
In order to determine the crystal
structure, X-ray diffraction was
measured and the diffraction pattern
of an iron piece is given here. Based
on this, calculate the lattice parameter
of this sample and determine its
crystal structure, knowing that lattice
parameter of FCC and BCC iron are
0.35 nm and 0.28 nm, respectively.
Hints: Assume n in Bragg's law =1, and wavelength of 0.154 nm.
