Question

1. What is the packing efficiency for a body centered cubic structure? Use the drawing of the unit cell to help you calculate this.

2. Titanium forms a body centered cubic structure. If the radius of a titanium atom is 1.47 angstroms, what is the density (grams per cm³) of titanium? (Hint: It may be easier to calculate moles per cubic angstrom first, and then convert into the desired units)
