Calculate the number of vacancies per cubic me￾ter in gold (Au) at 900C. The energy for vacancy 
formation is 0.98 eV/atom. Furthermore, the den￾sity and atomic weight for Au are 18.63 g/cm3
 (at 
900C) and 196.9 g/mol, respectively.

AI 0.1431 (b) Repeat this calculation at room temperature (298 K). Co 0.1253 HCP Cr 0.1249 BCC (c) What is the ratio of N/N (1357 K) and N/N (298 K)? Fe 0.1241 BCC Pt 0.1387 FCC Zn 0.1332 HCP 4.4 Calculate the number of vacancies per cubic me- ter in gold (Au) at 900°C. The energy for vacancy formation is 0.98 eV/atom. Furthermore, the den- sity and atomic weight for Au are 18.63 g/cm³ (at 900°C) and 196.9 g/mol, respectively. 45 Calculate the energy for vacancy formation in Which of these elements would form the following with nickel: (a) a substitutional solid solutic
