An X-ray diffraction peak for the (111) plane in silver (FCC) is found at 2θ = 38.2 ◦ when Cu K-α radiation is used. Given that the Cu K-α wavelength is 0.154 nm, compute the following for silver:

(a) Interplanar spacing (d) of the (111) planes (Bragg Law)

(b) Lattice constant (Equation 3.22)

(c) Radius of a silver atom

(d) Mass of a silver atom given that the density of silver is 10.5 g/cm3
