Vanadium has a body-centered cubic lattice, meaning there are 2 atoms per unit cell. The atomic mass of vanadium is approximately 50.94 g/mol. The volume of the unit cell is (305 pm)^3 = 2.835 x 10^-23 cm^3. Using the formula density = mass/volume, and converting the mass of 2 atoms of vanadium to grams, the density is calculated to be approximately 5.96 g/cm^3.
