As mentioned in the text, Ni3Al is used in the turbines of aircraft engines because of its strength and low density. Nickel metal has a cubic close-packed structure with a face-centered cubic unit cell, while Ni3Al has the ordered cubic structure shown in Figure 23.17(b) in the textbook. The length of the cubic unit cell edge is 3.53*10^-10 m for nickel and 3.56*10^-10m for Ni3Al calculate the density
