Question

Calculate the number of vacancies per cubic meter for some metal, M, at 773°C. The energy for vacancy formation is 0.97 eV/atom, while the density and atomic weight for this metal are 7.81 g/cm3 (at 773°C) and 67.81 g/mol, respectively.

Answer 1

0.112eV/atom

Step-by-step explanation:

since

p=m/v

then

pv=pv

7.81*0.97=67.81*V

V=7.58/67.81

V= 0.112eV/atom
