Structure Of Atom

The energy of one mole of photons of radiation of frequency \(2 \times 10^{12} \mathrm{~Hz}\) in \(\mathrm{J} ~\mathrm{mol}^{-1}\) is ___________. (Nearest integer)

[Given : \(\mathrm{h}=6.626 \times 10^{-34} ~\mathrm{Js}\)

\(\mathrm{N}_{\mathrm{A}}=6.022 \times 10^{23} \mathrm{~mol}^{-1}\)]
