Iron exhibits bcc structure at room temperature. Above C it transforms to fcc structure. The ratio of density of iron at room temperature to that at C (assuming molar mass and atomic radii of iron remains constant with temperature) is
To solve this problem, we need to find the ratio of the density of iron in bcc structure to that in fcc structure.The density of a crystal is given by:
