Question Six (a) At a temperature of 25°C, the number of vacancies, N., in a cobalt metal is estimated as: N, = N, exp(- Ns (fo) where, Q, = 0.85 ev/atom; kg = 8.62 x 10-5 ev/atom. K Given that Na = 6.023 x 10" atoms/mole, and pes= 8.85 g/cm', carry out the following: i. Determine the mass of cobalt that would contain 9.04 x 102 regular lattice sites. ii. Calculate the number of vacancies in the cobalt mass determined in (i) above.
