On the Difference of Energy between the Einstein and M{\o}ller   Prescription
  In some black hole solutions, these do not exist the same energy-momentum complexes associated with using definition of Einstein and M{\o}ller in given coordinates. Here, we consider the difference of energy between the Einstein and M{\o}ller prescription, and compare it with the energy density of those black hole solutions. We found out a special relation between the difference of energy between the Einstein and M{\o}ller prescription and the energy density for considered black hole solutions.
