Unformatted text preview: c. What is the volume of the cell in terms of r? d. What is the packing efficiency of the cell in percent? e. If the density of Co is 8.90 g/cm 3 , what is the atomic radius of a cobalt atom? f. The following data correspond to elemental cobalt: D (l) = 7.75 g/cm 3 , D (s at 23 C) = 8.90 g/cm 3 , mp = 1768 K, bp = 3200 K, critical pressure and temperature unknown. Generate a phase diagram for Co, labeling the solid, liguid and gas regions, and the melting and boiling points. p T g.
