 P: 118 Nevermind, I figured it out. In case anyone is interested, the density of a conventional cubic cell is going to be $$\frac{112 AMU}{a^3}$$ since the bcc lattice has to lattice points in a conventional cell. This must be equated with 7900 Kg/m^3. After conversion through dimensional analysis, you solve for a, which is the lattice parameter.
