Gold and silver both have the FCC crystal structure, and Ag forms a substitutional solid solution for all concentrations at room temperature. Compute the unit cell edge length for a 34 wt% Au - 66 wt% Ag alloy. The room-temperature density and atomic weight of Au are 19.32 g/cm3 and 196.97 g/mol, the room-temperature density and atomic weight of Ag are 10.49 g/cm3 and 107.87 g/mol, respectively.

In this problem, you are asked to find the unit cell edge length for a substitutional solid solution.

What is the average density of this solid solution?
