Question

Find the charge of I g ion ofN3

- in coulomb.​

Answer 1

Answer:Q=ne

n- represents no of electron.

e -represents the charge of electron.

1 mole - 14 gm of N3- ions

1 gm - 1/14 mole

1 gm- 1/14 * 6.022*10^23 atoms

1 atom of N3- have (7 +3) =10 electrons

therefore, 1 gm n^3- have 10* 1/14*6.022*10^23 electron

Q = (10*1/14*6.022*10^23)*(1.6*10^-19)= Answer

Explanation:

Answer 2

$\huge\red{\boxed{\bold{Solutions}}}$

• 1 ion of N^3- carries a charge of 3 × 1.602 × 10^19 coulomb

$\large\underline\mathrm{(Change \: on \: an \: electron \: = \: 1.602 \: × \: 10^-19 \:coulombs)}$

• 6.022 × 10^23 ions (1 g - ion or 1 mole) carry a charge of 3 × 1.602 × 10^23 coulombs

$\implies$ 2.894 × 10^5 coulombs.
