Question

Calculate the energy of one mole of photons of radiation whose frequency is 5(10^14) hertz?

Answer 1

Answer:

Energy ( E) of one photons is given by the expression

E=hv

h=6.626×10−34Js

v=5×1014S−1(given)

E=(6.626×10−34Js)×(5×1014S−1)

3.313×10−19J

Energy of one mole of photons

(3.313×10−19J)×(6.022×(6.022×1023mol−1)

199×51kJmol−1
