    For a body-centered unit cell, you have 2 atoms / cell. Radius can be calculated by the equation:

    3d^2 = (4r) ^ 2

    We calculate as follows:

    V = 1 / (8.57 g/cm^3 (1 mol / 92.91 g) (6.022x 10^23 atoms / 1 amol) (1 unit cell / 2 atoms)) = 3.60x10^-23 cm^3

    d = 3.30 x 10^-8 cm

    r = 1.43x 10^-8 cm
