Webx = (3.614 x 10¯ 19 J/photon) (6.022 x 10 23 photon mol¯ 1) = 217635.08 J/mol Dividing the answer by 1000 to make the change to kilojoules, we get 217.6 kJ/mol. A slightly different way would be to use Eλ = hc (with the wavelength in meters) and solve for E, then multiply the answer times Avogadro's Number. Finally, divide by 1000 to get kJ/mol. WebThis is the energy for one photon. (1.66 x 10¯15J) (6.022 x 1023mol¯1) = 9.98 x 108J mol¯1 This value is usually reported in kJ per mole: 9.98 x 105kJ mol¯1 Example #18:When it decays by beta decay, cobalt-60 also produces two gamma rays with energies of 1.17 MeV and 1.33 MeV.
