Manganese has a density of 7.44 g/cm^3. Given that the activation energy for vacancy formation is 1.1 eV/atom, calculate the number of vacancies per cubic meter of Manganese at 1200 degrees C. The atomic weight of manganese is 54.94 amu.
Answer the following.
a) Number of vacancies per cubic meter
b) Number of Mn atoms per cubic meter
c) diffusion coefficient of Mn
d) Temperature in K
