Question

Calculate energy of one mole of photons of radiation whose frequency is 5 x10 power 14 Hz.​

Answer 1

Answer:

Energy = h × v.

Then energy of one mole of photon = 199.51 kj mol-1.

Answer 2

Explanation:

Energy of 1 photon :

energy = frequency \times planks \: constant \\ energy = 4 \times 10 \times 6.626 \times 10 {}^{ - 34} \\ energy = 26.504 \times 10 {}^{ - 33}

The energy of 1 mole of photons :

1 mole = 6.022x10^23

= 26.504 \times 10 {}^{ - 33} \times 6.022 \times 10 {}^{23} \\ = 160\times 10 {}^{ - 10} joules
