Solved A Calculate The Equilibrium Number Of Vacancies Per Chegg Mae 20 winter 2011 assignment 3 solutions. 4.3 calculate the activation energy for vacancy formation in aluminum, given that the equilibrium number of vacancies at 500°c (773 k) is 7.57 × 1023 m 3. the atomic weight and density (at 500°c) for aluminum are, respectively, 26.98 g mol and 2.62 g cm3. Vacancy defect calculation #. the following is a calculation of the number of vacancy defects in a material. all crystalline and poly crystalline materials at temperatures above absolute zero contain vacancy defects. we can calculate the number of vacancies present in a material using the vacancy concentration equation below: n v n = e − q v r t. There are 2 steps to solve this one. experts have been vetted by chegg as specialists in this subject. calculate the equilibrium number of vacancies per cubic meter for silver (ag) at 600∘c. the energy for vacancy formation is 1.2ev atom. assume a density of 10.35 g cm3 and an atomic weight of 107.87 g mol for ag. The equilibrium number of vacancies can be calculated using the following equation: nv = nexp ( qv rt), where n is the total number of lattice sites, qv is the activation energy for vacancy formation, r is the gas constant, and t is the temperature in kelvin. 3.
