WebAbout WebSep 7, 2024 · How do you find energy in joules from wavelength? Use Planck’s equation E = h x c / λ and substitute the values of the wavelength (λ), Planck’s constant in joules (h = 6.6261 × 10⁻³⁴ J⋅s), and speed of light (c = 299792458 m/s). With these units, you’ll get an energy result in joules (J). That’s it!

WebThe units for the molar heat of fusion are kilojoules per mole (kJ/mol). Sometimes, the unit J/g is used. In that case, the term heat of fusion is used, with the word 'molar' being eliminated. See Example #3 below. The molar heat of fusion for water is 6.02 kJ/mol. As you go around the Internet, you will see other values used. WebFeb 6, 2024 · I am wondering if I would need to find out the wavelength of 1 mole of these photons first and then carry out the same steps as I did when looking for the energy of the single photon. So: if I converted nm to m first, then: 6.23x10^11m X 6.022x10^23 = _____m. and plug that into my E= h * c/wavelength = _____ and convert that to kilojoules?
