6) A hypothetical metal has the simple cubic crystal structure. If its atomic weight is 70.6 g/mol and the atomic radius is 0.128 nm, compute its theoretical density. (N=6.022 * 1023 atoms/mol) (Theoretical density-mass of atoms in unit cell/total volume of unit cell) 7) Write down the names of each crystal structure given below.
A hypothetical metal has the simple cubic crystal structure shown in Figure 3.3. If its atomic weight is 86.6 g/mol and the atomic radius is 0.169 nm, compute its density.
