How do you go from kJ mol to J photon?
The conversion to kJ/mol involves using Avogadro’s number and converting J to kJ: E (kJ/mol) = (3.713 × 10−19 J/photon)(6.022 × 1023 photon/mol)(10−3kJ/J) = 224 kJ/mol.
How do you convert change from kJ to J?
To convert a kilojoule measurement to a joule measurement, multiply the energy by the conversion ratio. The energy in joules is equal to the kilojoules multiplied by 1,000.
How do you calculate the energy of one mole of a photon?
The equation used to find the energy in a mole of photons is E= hc/lambda where h is Planck’s constant, c is the speed of light and is the wavelength of light.
How do you calculate the energy of a photon?
Calculation Theory
- Photon energy can be expressed using any unit of energy such as the electronvolt (eV) or the Joule (J).
- P = F × E (equation 3)
- P = F × hc/l (equation 4)
- P (mW) = 1.989 × 10-10 × F/l (nm) (equation 5)
How do you convert from photons to moles?
To find the energy of a photon, multiply Planck’s constant by the speed of light, then divide by the photon’s wavelength. For a mole of photons, multiply the result by Avogadro’s number.
How do you calculate the energy of one mole of photons?
How many kJ are there in aJ?

|---|---|---|
| From | Symbol | Result |
| 1 | aJ | 0.0000000000000000000010 |
How do you convert kilojoules to moles?
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”. To get the energy for one molecule, divide kJ/mol by Avogadro’s number, 6.022 x 1023.
How do you calculate energy in Joules per mole?
- The joule per mole (symbol: J·mol−1 or J/mol) is an SI derived unit of energy per amount of material.
- Since 1 mole = 6.0221407×1023 particles (atoms, molecules, ions etc.), 1 joule per mole is equal to 1 joule divided by 6.02214076×1023 particles, 1.66054×10−24 joule per particle.
