Some Basic Concepts Of Chemistry Question 182

Question: How much coulomb charge is present on 1g ion of $ {N^{3-}} $

Options:

A) $ 5.2\times 10^{6} $ Couloumb

B) $ 2.894\times 10^{5} $ Couloumb

C) $ 6.6\times 10^{6} $ Couloumb

D) $ 8.2\times 10^{6} $ Couloumb

Show Answer

Answer:

Correct Answer: B

Solution:

One ion carries $ 3\times 1.6\times {10^{-19}},coulomb $

Then 1 gm ion $ {N^{3-}} $ (1 mole) carries $ =3\times 1.6\times {10^{-19}}\times 6.02\times 10^{23} $

$ =2.89\times 10^{5},coulomb $
