How much energy is associated with a mole (6.022 x 1023) of photons with a frequency of 4.30 x 1014 s-1 ( Answer in kJ to 3 sig figs)
Energy of photons - -------------- (1)
n is number of photons,
h is plank's constant, 6.626 * 10-34 J s
v is frequency of light.
According to question,
n = 6.02* 1023
v = 4.30 * 1014 s-1
Substituting respective values in equation (1)
E = 6.02 * 1023 * 6.626 * 10-34 J s * 4.30 * 1014 ss-1
E = 171577.62 J = 171.578 kJ. (I kJ = 1000J)
