Question

Number of moles of electrons present in 34 g of $N H_{3}$ is:

Open in App

Solution

Number of moles of $N H_{3}$ = $\frac{34}{17}$ = 2 mol
Number of electrons in one molecule of $N H_{3}$ = 7 + 3 = 10 $e^{-}$
Number of electrons present in one mole of $N H_{3}$ = 10 $N_{A}$
Number of electrons present in 2 mole of $N H_{3} = 20 N_{A}$
Number of moles of electrons present in 2 mole of $N H_{3}$ = 20 mol
