## Question

### Solution

Correct option is

CuAg3 Au

Cu atoms are at eight corners of the cubic. Therefore, the number of Cu atoms in the unit cell = 8/8 = 1.

Ag atoms are at the face – centre of six faces. Therefore, its share in the unit cell = 6/2 = 3.

Au atoms are at the body centre,

∴ the number of Au atoms = 1

∴ The formula of the alloy is CuAg3 Au.
