Question

Quizplus · Accepted Answer

The energy of light (E) can be calculated using the equation E = hc/λ, where h is Planck's constant (6.626 x 10^-34 J·s), c is the speed of light (3.00 x 10^8 m/s), and λ is the wavelength in meters. For a wavelength of 360 nm (360 x 10^-9 m), the energy per photon is found to be approximately 5.52 x 10^-19 J. To convert this energy to kJ/mol, multiply by Avogadro's number (6.022 x 10^23 mol^-1), resulting in approximately 332 kJ/mol.
