How do you convert -2.1786*10^-18 J to kj/mole and this is the energy released when an electron is added to hydrogen nucleus. I been trying to figure this out for 30 mins and I still didn't get it please help

• Chemistry -

-2.1786E-18 J to AN electron x 6.02E23 will give you J/mol H atoms and that x 2 gives J/mol H2 and that x (1 kJ/1000) converts to kJ/mol
