Iron has a body centered cubic unit cell

WebApr 5, 2024 · Iron has a body-centred cubic unit cell with a cell edge of 286.65 pm. The density of iron is 7.87g cm –3. Use this information to calculate Avogadro’s number (At. mass of Fe = 56g mol –1 ). cbse class-12 1 Answer 0 votes answered Apr 5, 2024 by santoshjha (143k points) selected Apr 27, 2024 by Vikash Kumar The correct answer is WebThis is called a body-centered cubic (BCC) solid. Atoms in the corners of a BCC unit cell do not contact each other but contact the atom in the center. A BCC unit cell contains two atoms: one-eighth of an atom at each of the eight corners (8 × 1 8 1 8 = 1 atom from the corners) plus one atom from the center.
