Answer 1

Answer #1

λ ( in nm) = Nhc / ΔE = [1.19627x10⁵] / [Δ E_mole( KJ/mole ) ]

N= 6.02214 X 10²³ mole ^-1 , h = 6.62608 x 10 ^-34J sec , c=2.997925 x 10⁸ m / sec

By subtituting ΔE in KJ / mole we will get the λ ( in nm). (not given the series or energy in question)

[ Because ΔE_electron is negative for emission, and the energy of a photon cannot be negative,

ΔE_photon = - ΔE_electron = E_final - E_intial .

Since the energy can't be created nor destroyed, change in energy of the photon emitted will not be zero ]
