<u>Answer:</u> The molality of 
solution is 0.782 m
<u>Explanation:</u>
Molality is defined as the amount of solute expressed in the number of moles present per kilogram of solvent. The units of molarity are mol/kg. The formula used to calculate molality:
.....(1)
Given values:
Moles of = 0.395 mol
Mass of solvent (water) = 0.505 kg
Putting values in equation 1, we get:
Hence, the molality of solution is 0.782 m
According to the bohr model "The lower energy level into which the electron deflects from a higher energy level is designated by the quantum number nf" determines the shortest wavelength in a given series of wavelengths emitted by the atom.
By explaining that electrons move in fixed orbitals (shells) and not anywhere in between, Bohr theory amended the atomic structure model.
He also showed that each orbit (shell) has a fixed energy. Bohr refined Rutherford's model of the atom's nucleus to include electrons and their varying energy levels.
According to Rydberg formula
1/λ = R [1/ni² - 1/nf²]
λ = wavelength
R = Rydberg constant
ni & nf are integers or principal quantum numbers where nf > ni
So if we want wavelength(λ) to be shortest, then 1/nf should be zero.
In this way , it depends on nf and not on ni
That's why the lower energy level into which the electron deflects from a higher energy level is designated by the quantum number nf" determines the shortest wavelength in a given series of wavelengths emitted by the atom.

According to one acid base theory the forward reaction is classified as an acid base reaction because H2S is a H donor and CH3NH2 is a H acceptor.
According to the acid base theory; an acid is the proton donor or hydrogen ions donor while the base is the proton acceptor or hydrogen ion acceptor.
