Consider a hypothetical metal that has a simple cubic structure, a density of 9.62 g/cm3, and an atomic weight of 90.5 g/mol. If, at the melting temperature, one out of every 104 atom sites is a vacancy, determine the number of vacancies in one cubic meter of this material. Assume that the energy for the vacancy formation is 96,000 J/mol.

Answer should be in units of vacancies/m^3
