Radiation in the ultraviolet region of the electromagnetic spectrum is quite energetic. It is this radiation that causes dyes to fade and your skin to develop a sunburn. If you are bombarded with 1.00 mol of photons with a wavelength of 365 nm, what amount of energy, in kilojoules per mole of photons, are you being subjected to?

Respuesta :

Answer:

Explanation:

energy of one photon = hν

= hc / λ

h is plank constant , c is velocity of light and λ is wavelength .

= 6.6 x 10⁻³⁴ x 3 x 10⁸ / 365 x 10⁻⁹ J

= .0542 x 10⁻¹⁷ J

energy of 1 mole of photon = 6.02 x 10²³ x .0542 x 10⁻¹⁷ J

= .326 x 10⁶ J

= 326 x 10³ J

= 326 kJ .
