Calculate the fraction of atom sites that are vacant for copper (cu) at its melting temperature of 1084°c (1357 k). assume an energy

Calculate the fraction of atomic sites that are vacant for copper (Cu) at its melting temperature of 1084°C (1357 K). Assume an energy of vacancy formation of 0.90 eV/atom. Additionally, please repeat this calculation at room temperature (298 K). Lastly, what is the ratio of ( n_v / n(1357 \, \text{K}) ) and ( n_v / n(298 \, \text{K}) )?
