Calculate the energy of 1 mole of photon...

Calculate the energy of 1 mole of photons whose frequency is `6.0xx10^(14)` Hz.

Text Solution

Verified by Experts

Energy of 1 photon, `E=hv = (6.626 xx 10^(-34)Js) (6.0 xx 10^(14)s^(-1)) =3.97 xx 10^(-19)J`
Energy of 1 mole photons, `=(3.97xx10^(-19)J) (6.022 xx 10^(23)"mol"^(-1))=238.99"kJ mol"^(-1)`
