Question

the energy of one mole of photons of radiation whose frequencyis 5 x 10^14

Answer 1

Energy of 1 photon = hf
energy of 1 mole of photon = 6.022×10^23 × 6.63×10^(-34) × 5×10^14 Joule = (6.022×6.63×5) × 10^3 J = 199 kJ

So the energy of 1 mole of photon is 199kJ or You can say the energy of the photons is 199kJ/mol

Energy of 1 photon = hf

energy of 1 mole of photon = 6.022×10^23 × 6.63×10^(-34) × 5×10^14 Joule = (6.022×6.63×5) × 10^3 J = 199 kJ

So the energy of 1 mole of photon is 199kJ or You can say the energy of the photons is 199kJ/mol
