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 nm (b) the atomic radius for a rh atom nm

passing a magnet thought the

mixture , because iron gets attracted to magnet .
