Answer 2

Heya. !!!

_________________

==> A mole is defined as a no. which is equal to Avogadro no. 6.022 x 1023 which is used to count any microscopic particle, whether atom, molecules, or electrons etc.


==> Mole is basically  used in chemistry to express the unit of measurement for pure substances in the similar way as dozen or gross is used in our day to day life .Number of moles is calculated on the basis of the given mass and molar mass. i.eNumber of moles = given mass / molar massAs 1 mole of any substance contains 6.022 × 1023 particles {Where particles may refers to molecules ,ions,atoms or electrons.}
As, N has 7 electron as hydrogen conatian 1 electron
So, in total, 1 NH3 molecule conatin 7 + 3(1) electrons
= 10 electrons
As 1 mole of NH3 conatin →6.022 × 1023 molecules
Therefore nuber of electrons present in 6.022 × 1023 molecules of ammonia = 10 ×  6.022 × 1023 electrons
Hence, 1 mole of ammonia consist of 60.22  × 1023 electrons or 6.022 × 1024 electrons
