Answer:
2.89×10^5 coulomb
Explanation:
Charge on 1 mole of electrons=96500 coulomb
Charge in N^-3 means charge in 3 electrons
Charge in 1g ion means charge in 1 mole
Therefore the answer is 96500×3×1
=289500 coulomb
=2.89×10^5 coulomb

- Question⇒ How much coulomb charge is present on 1g ion of n^3?
- Your solution is right but the question you ask for might be
- for 1 g-ion. 1 g-ion = (weight in grams of sum of atomic weight of atoms making the ion.)
- Here N^3- has 14 amu so 1g-ion 14 gm.
- So here we have to find for 14g that is 1mole of nitride ion. 1 ion of nitride has =1.6 ×10^-19 × 3 C
- Therefore 6.022 × 10^23 ions has = 6.022 × 10^23 ×1.6 ×10^-19 × 3 C = 2.89 × 10^5 C.
