Question

copper
crystal has a face centred cubic lattice structure.Atomic
radius of copper atom is 128pm. What is the density
of copper metal? Atomic mass of copper is 63.5.​

Answer 1

The answer is 203.2*10^6 g/m3

Answer 2

Answer:

Given: Atomic radius of Cu atom = 128 pm = 128 x 10−10 cm z = 4 (FCC) Atomic mass of Cu = 63.5 To find: Density of Cu (d) = ? Formula: i. Face diagonal Calculation:

For FCC Lattice In face centred cubic arrangement face diagonal is four times the radius of atoms face diagonal.
