1.

5.98×10

^{19}2.

1.30×10

^{6}3.

= 246

## Answer

The value of frequency of a photon is 5.98x1019 s The expression for energy of a photon is as follows = (6.626×10-34 J. s) (5.98x 1019 s-1 41kJ6.023x103 -3.96x104 Jx 1KJx 1000 J mol E- 2.39x10 kJ/mol 2. The value of frequency of a photon is 1.30x10 s The expression for energy of a photon is as follows = (6.626x10-34 J s) (1.30×106 s-1) 8.61x10 Jx_1 kJ 6.023x103 1000 J mol E-5.19 x10-7 kJ/mol The value of wavelength is 246 m The expression for energy of a photon is as follows 246 m 21kJ 6.023x103 -8.07 x 10-28 J x-TKI-X 1000 J mol E-4.86x10- kJ/mol
