The electron in a hydrogen atom, originally in level n = 8, undergoes a transition to a lower level by emitting a photon of wave length 3745 nm. What is the final level of the electron?(c=3.00×10^8m/s, h=6.63×10^-34 J·s, RH=2.179×106-18J)a. 5 b. 6
c. 8
d. 9
e. 1
1 answer:
Explanation:
It is given that,
The electron in a hydrogen atom, originally in level n = 8, undergoes a transition to a lower level by emitting a photon of wavelength 3745 nm. It means that,
The amount of energy change during the transition is given by :
And
Plugging all the values we get :
So, the final level of the electron is 5.

Explanation:
mass of solute(KBr) = 3.73g
mass of solvent(H2O) = 131g
mass of solution = mass of solute + mass of solvent
= 3.73 + 131
= 134.73g
