The mass of an electron is {tex}9.1 \times 10^{-31}{/tex} kg
Therefore number of electrons in 1kg = {tex}1\over 9.1\times 10^{-31 }{/tex}electrons = {tex}1.09 \times 10^{30 }{/tex}
Electron Number of particles in 1 mole = {tex}6.023 \times 10^{23}{/tex} (Avagadro’s constant)
So , Number of moles ={tex} number \ of \ electrons\over Avagadro’s \ constant {/tex}= {tex}{1.09 \times 10^{30}\over 6.023 \times 10^{23}} = {1.8 \times 10^6}{/tex} electrons

The magnetic quantum number m determines the number of orbitals and their orientation within a subshell. Consequently, its value depends on the orbital angular momentum quantum number l. Given a certain l, m is an interval ranging from –l to +l, so it can be zero, a negative integer, or a positive integer.

1.Ideal gas has no definite volume while real gas has definite volume.
2.Ideal gas has no mass whereas real gas has mass.
3.Collision of ideal gas particles is elastic while non-elastic for real gas.
4.No energy involved during collision of particles in ideal gas. Collision of particles in real gas has attracting energy.
5.Pressure is high in ideal gas compared to real gas.
6.Ideal gas follows the equation PV=nRT. Real gas follows the equation (P + a/V2) (V – b) = nRT.

Phosphorus is sp3d hybridization. It forms 5 equivalent sp3d orbitals. Each of it contain an unpaired electron. The structure of PCl5 is trigonal bipyramidal in which three chlorine atioms are at the corners of triangle while two chlorine atoms are axial. Bond length of axial bond is greater than the length of equatorial bond to minimixe the bond pair – bond pair repulsion between axial and equatorial bonds.
