Question

Calculate the frequency of radiation for one mole photon whose energy is 199.5 ×10 3j

Answer 1

Answer:

=199.50×10−3jmol

Explanation:

The energy of one photon (E) =hv

Here, h=6.626×10

34

js

v=5×10

14

s

−1

E=6.626×10

−34

×5×10

14

3.313×10

−19

j

Thus the energy of one mole of photons is E×A

Where A is the Avogadro number

=3.313×10

−19

j×6.022×10

−23

mol

=199.50×10
