Answer :
Answer: Energy of a mole of these photons is [tex]0.368\times 10^6Joules[/tex]
Explanation:
The relationship between wavelength and energy of the wave for 1 mole follows the equation:
[tex]E=\frac{Nhc}{\lambda}[/tex]
E= energy
N= avogadros number =[tex]6.023\times 10^{23}[/tex]
[tex]\lambda [/tex] = wavelength of the wave =[tex]325\times 10^{-9}m[/tex] [tex]1nm=10^{-9}m[/tex]
h = Planck's constant = [tex]6.626\times 10^{-34}Js[/tex]
c = speed of light = [tex]3\times 10^8m/s[/tex]
[tex]E=\frac{6.023\times 10^{23}\times 6.626\times 10^{-34}\times 3\times 10^8m/s}{325\times 10^{-9}m}[/tex]
[tex]E=0.368\times 10^6Joules[/tex]
Thus the energy of a mole of these photons is [tex]0.368\times 10^6Joules[/tex]
