Calculate the number of Frenkel defects per cubic meter in zinc oxide at 904˚C. The energy for defect formation is 2.51 eV, while the density for ZnO is 5.55 g/cm3 at this temperature. The atomic weights of zinc and oxygen are 65.41 g/mol and 16.00 g/mol, respectively.

defects/m³

Explanation:

Let's first determine the number of lattice sites per cubic meter; and which can be denoted as:

lattice sites/m³

Now, to Calculate the number of Frenkel defects per cubic meter in zinc oxide at 904˚C, we have:

defects/m³

Hence, the  number of Frenkel defects per cubic meter in zinc oxide at 904˚C  = defects/m³
