The concentrations : 0.15 M
pH=11.21
<h3>Further explanation</h3>
The ionization of ammonia in water :
NH₃+H₂O⇒NH₄OH
NH₃+H₂O⇒NH₄⁺ + OH⁻
The concentrations of all species present in the solution = 0.15 M
Kb=1.8 x 10⁻⁵
M=0.15
![\tt [OH^-]=\sqrt{Kb.M}\\\\(OH^-]=\sqrt{1.8\times 10^{-5}\times 0.15}\\\\(OH^-]=\sqrt{2.7\times 10^{-6}}=1.64\times 10^{-3}](https://tex.z-dn.net/?f=%5Ctt%20%5BOH%5E-%5D%3D%5Csqrt%7BKb.M%7D%5C%5C%5C%5C%28OH%5E-%5D%3D%5Csqrt%7B1.8%5Ctimes%2010%5E%7B-5%7D%5Ctimes%200.15%7D%5C%5C%5C%5C%28OH%5E-%5D%3D%5Csqrt%7B2.7%5Ctimes%2010%5E%7B-6%7D%7D%3D1.64%5Ctimes%2010%5E%7B-3%7D)

Answer:
1.
2.
3.The electron affinity of 
is zero.
4.
Explanation:
1.
<u>Electron affinity:</u>
It is defined as the amount of energy change when an electron is added to atom in the gaseous phase.
The electron affinity of 
is as follows.
2.
<u>Ionization energy</u>:
Amount of energy required to removal of an electron from an isolated gaseous atom.
The third ionization energy of Titanium is as follows.
3.
The electronic configuration of Mg: 
By the removal of two electrons from a magnesium element we get ion.
has inert gas configuration i.e,
Hence, it does not require more electrons to get stability.
Therefore,the electron affinity of is zero.
4.
The ionization energy of 
is follows.
Potassium outermost electron occupy "4s" orbital
