Question

14.
The energy of one mole photons of radiation having
frequency 5.01×104^14Hz is :
(1) 160 KJ mol-1
(2) 180 KJ mol-1
(3) 200 KJ mol-1
(4) 220 KJ mol-1​

Answer 1

Answer:

200 KJ/mole

Explanation:

energy = number of photons * energy in one photon

        = n h v

        = 6.023 * 10²³  *  6.626 * 10⁻³⁴ * 5 * 10¹⁴  Joules

        =  199.54 KJoules mol-1

        ≈ 200 KJoules mol-1
