Aground state hydrogen atom absorbs a photon of light having a wavelength of 92.30 nm. it then gives off a photon having a wavelength of 1820 nm. what is the final state of the hydrogen atom?

n=5

Explanation:

We use the Rydberg formula to solve this problem:

1 / λ =

Where λ is the wavelength of absorption/emission, RH is a constant (1.097*10⁷m⁻¹), n₁ is the state of minor energy and n₂ is the state with higher energy.

1 / 92.3 * 10⁻⁹m = 1.097*10⁷m⁻¹ *

0.988 =

n_{2}^{2}=83.333\\n_{2}=9.12[/tex]

So after absorbing the wavelength of 92.30 nm the state of the hydrogen atom is n=9

So the final state of the hydrogen atom is n=5

yes the answer is total mass in unchanged   : )
