WebIt was originally defined as the energy in one mole of photons ( 6.022 × 1023 photons). [1] [2] Because energy is inversely proportional to wavelength, the unit is frequency dependent. This unit is not part of the International System of Units (SI) and is redundant with the joule. WebA laser pointer typically has a power rating of 1 mW, or 0.001 Joules per second. This means that every second a laser pointer emits a number of photons equal to (3.2x10 18 photons/J)(0.001J/s) = 3.2x10 15 photons/s. Now that we know how many photons are produced per second, we need to know how much momentum is carried by each photon. WebE (kJ/mol) = (3.71 3 × 10 −19 J/photon) (6.022 × 10 23 photon/mol) (10 −3 kJ/J) = 224 kJ/mol .
