What will be the concentration of ammonium ions (NH₄⁺) in moles per litre units in a solution having 10 ppm of ammonium ions ?

Solubility of gases (e.g oxygen in atmosphere) in liquid (e.g water in a river) is best explained by -

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R
Assertion A: For a binary solution the chemical potential of one component of the mixture cannot change independently of the chemical potential of the second component.
Reason R:
In the light of the above statements, choose the most appropriate answer from the options given below:
