Bond  energy  which  is   also  known   as   bond  enthapy  is  the  average    value  of  the  gas  phase  bond  dissociation  energy usually  at  298k  for  all bond  of  the  same type  within  the   same  chemical  species.

water  has  two  H-O  bond  that  is  O-H-O
bonb  energy  for  H-O  is  464k/j
therefore  o-H-O  =2  x464  =928  kj/mol 
since bond  breaking  process  is  exothermic   the  bond   energy  = -928  kj/mol

The bond energy per mole for forming all the bonds of water molecules is equal to -928  kJ/mol.

What is bond energy?

Bond energy can be defined as the amount of chemical energy that is required to break one mole of a given chemical bond.

The bonding of atoms in a water molecule.

In a water molecule, two (2) atoms of hydrogen bonds with an atom of oxygen through two (2) covalent bonds (O-H-O). Additionally, the two (2) atoms of hydrogen are bonded to an oxygen atom by polar covalent bonds while neighboring water molecules are held together by hydrogen bonds.

Scientifically, the bond energy for a mole of H-O is equal to 464 kilojoules. Therefore, O-H-O = [tex]2 \times 464[/tex] = -928  kJ/mol.

Note: The negative sign indicates that the bond breaking process is an exothermic reaction.
