52. The structure of a ternary salt consists of anions, X, arranged in a cubic close-packed array (as shown below) and cations A and B (the cations are not shown). Cation A occupies all of the octahedral holes in the lattice. What fraction of the tetrahedral holes must be occupied by cation, B, to give an emprical formula of ABX? A. All of them B. one-half C. one-fourth D. one-eighth
