Consider a hypothetical metal that has a density of 11.6 g/cm3, an atomic weight of 157.6 g/mol, and an atomic radius of 0.127 nm. Compute the atomic packing factor if the unit cell has tetragonal symmetry; values for the and lattice parameters are 0.523 nm and 0.330 nm, respectively.

Explanation:

From the question we are told that

Density of metal

Atomic weight of

Atomic radius of

Lattice parameters=>  and

Generally the equation for atomic packing factor is mathematically given as

Generally the equation for number of atoms N is mathematically given as

Therefore APF(atomic packing factor)
