1) Tungsten crystallizes in a cubic unit cell with an esge length of 3.165 (Angrstroms)and with a tungsten atom on each of the corners of the unit cell and in the center of the unit cell(BCC structure).
(2) Calculate the density of tungsten.
Not sure why this was added to the question but if you would please explain it to me. How can you use Avogadro's number and the molar mass to determine the mass of tungsten in one unit cell?
