Calculate the energy of one mole of photons of radiations whose frequency is `3 xx 10^(12) Hz`

Explanation

`E = hc = 6.625 xx 10^(-34) Js xx 3 xx 10^(12) s^(-1)`
`= 1.9875 xx 10^(-21) J` form one photon
Energy of one mole of photons is
= Energy of one photon X avogadro number
`=1.9875 xx 10^(-21) J xx 6.023 xx 10^(23)`
`=1.1970 xx 10^(3) J mol^(-1)`
