2. Use the provided information to answer the following questions pertaining to the crystal structure of anatase (TiO2): Formula Unit: anatase (TiO2) Space Group: 14,/amd Cell Contents: 4 formula units per cell Cell Dimensions: a = 3.7858, c = 9.5148 Atomic Positions: Ti in (4a): (0,0,0), [(0, 72, 74); +I] O in (8e): (0, 0, z), (0, 0,), (0,1/2, z+ 74), [(0, 72, 74 - Z); +I] z=0.2 a) From which of the 32 Point Groups was this Space Group derived? b) What is the Bravais Lattice associated with this structure? c) Calculate the volume (cm) of this unit cell. HINT: V= a'c is sufficient in this case. d) Given the atomic weights of Ti (47.87 g/mol) and O (16.00 g/mol), calculate the theoretical density (g/cm) of anatase TiO2 HINT: P =
