Question

Calculate the amount of energy for 1 mole of photon if radiation having wavelength 200 mm

Answer 1

buddy here is your answer

Calculate the energy of one mole of photons of radiation having wavelength of 200 nm.

We know,

E (Energy of Photon) = hc/ λ

= 6.63 x 10-34 x 3.0 x 10 8/ 200 x 10-9

= 9.94 x 10-19 joules.

Energy of one mole of Photons = 6.022 x 1023 x 9.94 x 10-19

hope it helped you!
