How much energy (in kJ) do 3.0 moles of photons, all with a wavelength of 655 nm, contain?

If 310 kJ/mol of energy is required to make the reaction proceed, what wavelength of light is necessary to provide this energy?

The energy of a single photon is 2.441 × 10⁻²⁰ J. What is the energy of one mole of these photons, in kilojoules?

Ultraviolet radiation and radiation of shorter wavelengths can damage biological molecules because these kinds of radiation carry enough energy to break bonds within the molecules. A typical carbon–carbon bond requires 348 kJ/mol to break. What is the longest wavelength of radiation that can break a carbon–carbon bond?

Ultraviolet radiation and radiation of shorter wavelengths can damage biological molecules because they carry enough energy to break bonds within the molecules. A carbon-carbon bond requires 348 kJ/mol to break. What is the longest wavelength of radiation that can still break a carbon-carbon bond?

What is the energy in kJ/mol of photons with a wavelength of 450 nm?

What is the frequency of a photon emitted when an electron in a hydrogen atom transitions from n = 3 to n = 2? (R_H = 1.097 x 10^7 m^−1)

What is the frequency of light when the energy for a mole of photons is 1.55 x 10^13 J? (Use Planck's constant, h = 6.626 x 10^-34 J·s, and Avogadro's number, 6.022 x 10^23 mol^-1)

What is the frequency of light when the energy of a single photon is 1.48 × 10⁻¹⁵ J? (Use Planck's constant, h = 6.626 × 10⁻³⁴ J·s)

What is the total energy (in kJ) of 1.0 mol of photons with a frequency of 2.75 × 10^14 Hz?

What total energy (in kJ) is contained in 1.0 mol of photons, all with a frequency of 2.75 × 10^14 Hz?

Convert 4.5 x 10^-15 J/photon to wavelength in nm. Which of the following is the correct wavelength?

Electromagnetic radiation with a wavelength of 531 nm appears as green light to the human eye. The energy of one photon of this light is 3.74 × 10^-19 J. Thus, a laser that emits 1.3 × 10^-2 J of energy in a pulse of light at this wavelength produces how many photons?

How much energy is contained in one mole of X-ray photons with a wavelength of 0.280 nm in kJ/mol?

What is the energy in kJ/mol of infrared radiation with a wavelength of 1.51 × 10⁻⁶ m?
