Some oxide superconductors adopt a crystal structure similar to that of perovskite (CaTiO3). The unit cell is cubic with a Ti4+ ion in each corner, a Ca2+ ion in the body center, and O2- ions at the midpoint of each edge. (a) Is this unit cell simple, body-centered, or face-centered? (b) If the unit cell edge length is 3.84 Å, what is the density of perovskite (in g/cm3)?
