An alloy of copper, silver and gold is found to have copper atoms at ccp lattice, silver atoms at edge centers and gold a body center of unit cell. The simplest formula of the alloy is

Options:

Answer:

Solution:

Number of Cu-atoms at ccp lattice (corner + face)
$= 8 \times \frac{1}{8} + 6 \times \frac{1}{2} = 4$
Number of Ag-atoms
$= \frac{1}{4} \times 12 = 3$
Number of Au-atoms = 1
Simplest formula $= C u_{4} A g_{3} A u$
