Answer 2

Bonjour!

According to the question we have to calculate the energy of one mole of photons whose radiation frequency is 5 × 10¹⁴ Hz

Formula for calculating energy.

E = hv

E => Energy

h => Planck's constant = 6.626 × 10-³⁴ Js

v => Frequency = 5 × 10¹⁴ Hz (Given)

Therefore,

E = 6.626 × 10-³⁴ × 5 × 10¹⁴

= 3.313 × 10^-19

Now we have to find the energy of 1 mole so we will multiply the Energy by NA(Avogadro's number = 6.022 × 10²³)

So, Energy of 1 mole of photons = 3.313 × 10^-19 × 6.022 × 10²³

= 19.950886 × 10⁴

= 1.9950886 × 10^5 KJ mol-¹

Hope this helps...:)
