Question

find the charge of one gram ion of nitride in coloumb​

Answer 1

Explanation:

one N³- has 3 extra electrons so 1 mole must contain 3 x 6.022 x 10²³ electrons. 1 mole of N3– is 7 g

Therefore,no of charge=3 x 6.022 x 10²³/7 n= 2.58 x 10²³ electrons in 1g

But e= 1.6 * 10-¹9 C

Therefore total charge,

q= ne

= 4.12 x 10⁴ C
