Q2.) Iodine has an orthorhombic unit cell for which the a, b, and c lattice parameters are 0.479, 0.725, and 0.978 nm, respectively. If the atomic packing factor, atomic radius and atomic weight of iodine are 0.547, 0.177 nm and 126.9g/mol. (For orthorhombic a #b #c and a =ẞ= y=90º) a) Determine the number of atoms in each unit cell 3) C 39
