Calculate the energy emitted when electron of 1.0 gm atom of Hydrogen undergo transition giving the spectrtal lines of lowest energy is visible region of its atomic spectra. Given that, `R_(H)`=`1.1xx10^(7) m^(-1)`,` c=3xx10^8m//sec`,` h=6.625xx10^(-34) Jsec`.

Text Solution

Verified by Experts

The correct Answer is:
`1.827xx10^(5)J//mol`
`DeltaE = 13.6[(1)/(9)-(1)/(4)]xx96.3368kJ//"mole"`
`13.6[(4-9)/(36)]xx96.368=182.074`
`1.827xx10^(5)J//"mole"`
