A solid crystallinses as cubic close packing of `O^(2-)` ions. `A^(x+)` ions occupy 25% of the tetrahedral voids and `B^(y+)` ions occupy 50% of the octahedral voids. The suitable values of x and y are:

Crystal structure of the oxide AB_(2)O_(4) is bassed on the cubic close packed (ccp) array of O^(2-) ions, with A^(2+) ions occupying some tetrahedral voids and B^(3+) ions occupying some octahedral voids. If a crystal of this oxide contains 1 mol AB_(2)O_(4) formula unit, then calculate (1) total number of voids in the crystal (2) total number of tetrahedral voids occupied by A^(2+) ions (3) total number of octahedral voids occupied by B^(3+) ions.

In a compound oxide ions are arranged in cubic close packing arrangement. Cations A occupy one-sixth of the tetrahedral voids and cations B occupy one-third of the octahdral voids. The formual of the compound is A_(x), B_(y), O_(z) then find the value of x + y + z
