Unformatted text preview: 3 expected in copper at 1080 C° (just below the melting temperature). The energy for vacancy formation is 20,000 cal/mol. 4-5 BCC lithium has a lattice parameter of 3.5089 ×10-8 cm and contains one vacancy per 200 unit cells. Calculate (a) the number of vacancies per cubic centimeter; and (b) the density of Li....
