Answer 2

Answer:

The number of electrons in $1mol$ of $N_{3} ^{-}$ ions measured are $1.32\times 10^{25}$ electrons.

Explanation:

Given,

The number of moles of azide ions( $N_{3} ^{-}$ ) = $1 mol$

The number of electrons in $1mol$ of $N_{3} ^{-}$ ions =?

As we know,

• In an azide ion, $3$ nitrogen atoms are present with one negative charge.
• In one nitrogen atom, $7 electrons$ are present.

Therefore,

• The total number of electrons in one $N_{3} ^{-}$ ion = $3\times number of N-atoms+ cationic charge$ = $3\times 7 + 1$ = $22 electrons$.

Now, as we know,

• 1 mole = $6.022\times 10^{23}$ electrons

Thus,

• 1 mole of $N_{3} ^{-}$ ions = $22 \times 6.022\times 10^{23}$ electrons = $1.32\times 10^{25}$ electrons.

Hence, the number of electrons in $1 mol$ of $N_{3} ^{-}$ ions = $1.32\times 10^{25}$ electrons.
