A hypothetical salt AxBy crystallizes in the cubic syatem. The unit cell mass has atoms of A at each corner plus on at (1/2,1/2,/1/2) and atoms of B at positions (0,1/2,1/2).
(1) Locate the atoms A and B in the unit cell
(2) Give values to x and y in the AxBy
(3) If the edge of the atomic weights is 6 amperesand the atomic weight of A and B 40 and 120 respectively, calculate the density of AxBy
(4) What is the coordination number of A and for B, and describe the geometric figure that corresponds to the arrangement of A atoms around B atom
