In an alloy of gold and cadmium, gold crystallizes in cubic structure occupying the corners only and cadmium fits into the face centre voids. What is quantitative composition of the alloy?

In an alloy of gold and cadmium, gold crystallizes in cubic structure occupying the corners only and cadmium fits into the face centre voids.

Number of gold atoms     =1/8 x 8 =1Au

Number of candium atoms =1/2 x 6 =3Cd

Hence, quantitative composition on = AuCd3
