An isotope of hydrogen atom is  represented as X which follows Bohr's model and exists as diatomic gaseous molecule `X_(2)`. Also the normal boiling point of a compound `X_(2)O` liquid is found to be `101^(@)` C and that of solution obtaind on dissolving `0.1` moles of `NaCl` in `1` kg of `X_(2)O`liquid is `101.4^(@)C`. It is also known that the ionization energy of X is equal to `14 eV`.   The energy required to excite electron from ground state of IInd excited state is given by :
