Transcribed Image Text:1-When silver crystallizes, it forms face-centered cubic cells. The unit cell
edge length is 5.34 Å. Calculate the density of silver. the molecular weight
„M=107.868 g/mol.
2-Nickel crystallizes in a face-centered cubic array of atoms in which the
edge of the unit cell is 0.45 nm. Calculate the density of the metal. Since the
molecular weight ,M= 58.69 g/mol.
3- The atomic radius of an iron atom is 1.238 * 10-1º m. Iron crystallizes as
BCC. Calculate the lattice parameter of the unit cell, a. How many atoms
are contained within the BCC unit cell ? Also find the atomic packing
factor ?
