What is the equilibrium number of vacancies, per cubic metre, for copper at 628 °C. Given: Activation energy per vacancy 0.8 eV/atom Atomic weight of copper = 58.5 g/mol and density at the given temperature is 8.40 g/cm³ Boltzmann's constant kg= 1.38x10-23 J/atom.K = 8.62x10-5 eV/atom.K Your answer should be in scientific notation with 5 significant figures. The following example shows the format in which you should input your answer: 1.2475e8. Useful formulae: NAA density (p) where Avagadro's number Na= 6.022 x 1023 atoms/mol V.Na Np = exp NA
