molar mass Fe = 55.845 g/mol
1 mole = 6.022x1023 entities
entities = atoms, ions, molecules, formula units
density of solid Fe = 7.87 g/cm3
Calculate the atoms present per cubic centimeter of Fe
atoms/cm3 = 8.486x1022 Fe atoms/cm3
Calculate the number of unit cells are present per cubic centimeter of Fe
recall the # of atoms present per 1 BCC unit cell: corner atoms contribute 1/8 and the center atom contribute 1
# of atoms = 2 per 1 unit cell
The density of solid Fe is 7.87 g/cm3. How many atoms are present per cubic centimeter of Fe? As a solid, Fe adopts a body-centered cubic unit cell. How many unit cells are present per cubic centimeter of Fe? What is the volume of a unit cell of this metal? What is the edge length of a unit cell of Fe?
