CaTiO3 has a perovskite structure with Ca+2 ions (radius=0.106 nm; atomic wt = 40.08)) at the corners of the cubic unit cell, O-2 ions (radius=0.132 nm; atomic wt = 16.00) on each face of the cube, and Ti+4 ions (radius= 0.064 nm, atomic wt = 47.90) at the center of the cube. Using this information calculate the density of CaTiO3 in grams per cm3.
