26. The crystal lattice of platinum at normal pressure (1 atm) and temperature (298 K) is shown below. The platinum atoms adopt a lattice structure that is cubic (1) The coordination number of the platinum atom in the lattice is: (1) Each atom at the corner of the cube is shared among unit cells (1) Each atom at the center of a face is shared among unit cells (1) The total number of platinum atoms/unit cell is: The mass of the unit cell is (please report in amu): The edge length of the unit cell is determined from X-ray measurements to be 3.924 8. The volume of the unit cell is therefore: A (1) The platinum atoms occupy % of the available unit cell volume (1) The remaining % of the unit cell volume is unoccupied space (1) The volume of the platinum atoms only/unit cell is A' (1) Assuming the platinum atoms are perfect spheres, the platinum atom radius is (Given: volume of a sphere is 4/3Ar”). Please show all work below. (3) А Given 1 A = 10% cm and 1 amu = 1.66054 x 1024 g, please convert your platinum density from amu/A to g/cm'. Please show all work below. (2)
