Question

Copper crystal has a face- centred cubic lattice structure. Atomic radius of copper atom is 128pm. Calculate the density of copper. Atomic mass of copper= 63.5​

Answer 1

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.
