Answer:
The energy of a mole of photon is 2.99x10⁵ J.
Explanation:
First, we need to remember that in 1 mol of photons we have 6.02x10²³ photons.
The energy is given by:
[tex] E = Nh\nu [/tex]
Where:
h: is the Plank's constant = 6.62x10⁻³⁴ J.s
ν: is the frequency = 7.5x10¹⁴ Hz
N: is the number of photons = 6.02x10²³ photons
Hence, the energy of a mole of photon is:
[tex] E = Nh\nu = 6.02 \cdot 10^{23}*6.62 \cdot 10^{-34} J*s*7.5 \cdot 10^{14} Hz = 2.99 \cdot 10^{5} J [/tex]
I hope it helps you!
