Given that `Deltah_(f)(H)=218 kJ//mol`. Express the `H-H` bond energy in `K cal//mol`

Given that DeltaH_(f) (H) = 218 KJ//mol , express the H-H bond energy in Kcal//mol.

Consider the following data: Delta_(f) H^(2) (N_(2)H_(4), l) =50kJ//mol,, Delta_(f) H^(@) (NH_(3), g)=-46 kJ//mol , B.E. (N-H)= 393kJ//mol and B.E. (H-H)= 436 kJ/mol, also Delta_("vap") H (N_(2)H_(4),l)= 18kJ//mol . The N-N bond energy in N_(2)H_(4) is
