Silver and palladium both have the FCC crystal structure and

Silver and palladium both have the FCC crystal structure and Pd forms a substitutional solid solution for all concentrations at room temperature. Compute the unit cell edge length for a 75 wt% Ag–25 wt% Pd alloy. The room-temperature density of Pd is 12.02 g/cm3, and its atomic weight and atomic radius are 106.4 g/mol and 0.138 nm, respectively.
