The formula to calculate the energy per photon from the energy per mole is:
\[ E_p = \frac{E_m \times 1000}{N_A} \]
Where:
Let's say the energy per mole is 500 kJ/mol. Using the formula:
\[ E_p = \frac{500 \times 1000}{6.02214076 \times 10^{23}} = 8.30 \times 10^{-19} \, \text{J} \]
So, the energy per photon is approximately \(8.30 \times 10^{-19}\) J.
