Copper and platinum both have the FCC crystal structure and Cu forms a substitutional solid solution for concentrations up to approximately 6 wt% Cu at room temperature. Compute the unit cell edge length for a 95 wt% Pt-5 wt% Cu alloy. Assume that densities of Cu and Pt are 8.94 and 21.45 g/cm3 and atomic weight are 63.55 and 195.08 g/mol, respectively.
