Question

Calculate the energy of one mole photons of radiation. Whose frequency is $5\times {10}^{10}{S}^{-1}$

$(whereh=6.62\times {10}^{-34}{J}_s)$ :

Answer 1

Energy of Photon is given by $E$ = $h$$\nu$

where is h is Plancks Constant = 6.626 x ${10}^{-34}$ $m^{2}kg/sec$

$\nu$ = 5 x ${10}^{10}$ $S^{-1}$

E = 6.626 x ${10}^{-34}$ x 5 x ${10}^{10}$ J

E = 33.18 x ${10}^{-24}$ J
