हिन्दीCalculate the energy of one mole of photons of radiation whose frequency is \( 5 \times 10^{14} \text{ Hz} \).
Correct answer · Option 2
\( 199.51 \text{ kJ mol}^{-1} \)
Explanation
Energy of one mole = \( N_A h\nu = 6.022 \times 10^{23} \times 3.313 \times 10^{-19} = 199.51 \text{ kJ mol}^{-1} \).
