31 Ιουλ 2024 · This is Omni's wavelength to energy calculator, a tool that instantly calculates a photon's energy from its wavelength. By using Planck's equation, this tool will help you determine a photon's energy in joules (J), electronvolts (eV), or its multiples.
ElectronVolt - kJ/mol calculator. Added Aug 1, 2010 by Philgee in Chemistry. Quite often (eg in thermal desorption spectroscopy) energies like activation or desorption energy are stated in either electron volt or kJ/mol. Send feedback | Visit Wolfram|Alpha.
Kilojoules per mole (kJ/mol) A Joule, J, is the SI unit of energy and is defined as one kg.m 2 /s 2. The prefix "kilo" means 1,000, so one kJ = 1,000 J. As the energies associated with a single molecule or atom are quite small, we often find it easier to discuss the energy found in one mole of the substance, hence "per mole".
eV/particle to J/mol Conversion. The abbreviation for eV/particle and J/mol is electron volt per particle and joule per mole respectively. 1 eV/particle is 96492 times bigger than a J/mol.
21 Οκτ 2024 · To calculate wavelength from the energy of a photon: Convert the photon's energy into joules. Divide the speed of light, equal to 299,792,458 meters per second, by the photon's energy. Multiply the resulting number by Planck's constant, which is 6.626×10 −34 J/Hz.
Energy converter tool adapted from Colby College. Enter your energy value in the box with the appropriate units, then press "tab" or click outside of the input box. Hartrees (Eh) eV. kJ/mol. kcal/mol.
29 Ιουλ 2024 · The energy of a single photon of green light of a wavelength of 520 nm has an energy of 2.38 eV. You can use the photon energy calculator to explore further the relationship between the photon energy and its frequency or wavelength.
