We have a metal alloy (bcc) that
Metal A is FCC, 30 atom% (40.244 wt%), r=0.2 nm, A = 55 g/mol
and, Metal B is BCC, 70 atom% (59.756 wt%), r=0.24 nm, A = 35 g/mol
1. Find the volume per atom for metal A and metal B by dividing the unit cell volume by the number of atoms in the unit cell. Put your units in cm3/atom.
2. Use the atom% values and the answers to (a) to find the average volume per atom
