Question: the metal rhodium has an fcc?
Answer: The metal rhodium (Rh) has an FCC crystal structure. If the angle of diffraction for the (311) set of planes occurs at 36. 12∘ (first-order reflection) when monochromatic x-radiation having a wavelength of 0.0711 nm is used, compute the following: (a) The interplanar spacing for this set of planes.
