Answer to Question #171782 in Physical Chemistry for You
Iridium crystals have a cubic unit cell. The first six observed Bragg Diffraction angles from a powdered sample using X-rays with wavelength = 165.8 pm are 21.96o, 25.59o,37.65o,45.74o, 48.420 and 59.74o. Determine the type of cubic unit cell and its length.
The h2+k2+l2 calculated are only allowed in face-centered cubic crystals. The length calculated is 3.8390 angstrom.
