The ground-state electron configurations of transition metal ions are diamagnetic [Kr]
. The ion is diamagnetic because there all electrons are paired.
- A magnetic field repels diamagnetic materials because it induces an opposing magnetic field in them when it is applied, which produces a repelling force.
- In contrast, a magnetic field draws paramagnetic and ferromagnetic materials together.
- All materials experience the quantum mechanical phenomenon known as diamagnetism, which is the only source of magnetism in a material.
- The magnetic dipoles within paramagnetic and ferromagnetic materials exert an attracting force that outweighs the modest diamagnetic force.
- Diamagnetic materials have a magnetic permeability that is less than vacuum, or 0.
- Although superconductors behave as strong diamagnets, diamagnetism is often a modest effect that can only be observed by sophisticated laboratory equipment.

Answer:
The volume of the flask is<u> 20.245 litres .</u>
Explanation:
We are given with following information-
-------- 1
where R =
Molar mass of
The given chemical equation is -
--------- 2
Now , calculation -
Mass of formed = 118g
Molar mass of =
Mole =
Therefore , moles of formed =
From equation 2 , we get to know that ,
2mole formed from 5 mole
Therefore , mole
formed from
mole
Moles of used =
R=
Pressure (P)= 1.85atm
Temperature (T)= 322K
Moles of (n)=
moles
Applying the formula above in 1 equation , that is
PV = nRT
putting the given values -
V = 20.245 litres.
Hence , the volume of the flask is <u>20.245 litres . </u>
