The fraction of the atom that are vacant for the copper atom at its melting temperature is [tex]4.57\times 10^{-4}[/tex].
The fraction of the atom that are vacant for the copper atom at its melting temperature is determined using the equation below;
[tex]\frac{N_v}{N} = e^{(\frac{-Q_v}{KT} )[/tex]
where;
The fraction of the atom that are vacant for the copper atom at its melting temperature is calculated as follows;
[tex]\frac{N_v}{N} = e^{(\frac{-0.9}{8.62 \times 10^{-5} \times 1357} )}\\\\\frac{N_v}{N} = 4.57\times 10^{-4}[/tex]
