AI Generated Solution

To determine the formula of the compound alloy of gold (Au) and copper (Cu) that crystallizes in a cubic lattice, we need to analyze the positions of the atoms within the lattice structure. ### Step 1: Identify the positions of the atoms - Gold (Au) atoms occupy the corners of the cube. - Copper (Cu) atoms occupy the centers of each of the cube faces. ### Step 2: Calculate the contribution of gold atoms - In a cube lattice, there are 8 corners. ...
