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. high wycombe bowling
