An alloy named "Cylon" is composed of 25 wt.% of metal A and 75 wt.% of metal B. If the densities of metals A and B are 6.17 and 8.00g/cm^3, respectively, whereas their respective atomic weights are 171.3 and 162 /mole, determine whether the crystal structure for this alloy is simple cubic, face centered cubic, or body centered cubic. Assume a unit cell edge length (e.g lattice parameter a_o) of 0.332 nm.
