Question

no: of ions are present in one mole of sodium chloride.​

Answer 1

Answer:

6.022 X 10²³

Explanation:

Given: n (number of moles) = 1

           N (number of particles) = ?

           N₀ (Avogadro's number) = 6.022 X 10²³

We know that the number of moles is equal to the given number of particles divided by the Avogadro's number.

Remember this formula  n = N/N₀

Substituting the values, we get

1 = N/ 6.022 X 10²³

N = 6.022 X 10²³ X 1

Thus the number of ions present in one mole of NaCl is 6.022 X 10²³.

This is the mathematical calculation of the question which proves why the answer is the Avogadro's constant.

But we can simply write 6.022 X 10²³ without thinking because we know that 1 mole of a substance has exactly 6.022 X 10²³ particles.

The above mathematical calculation will help you to understand the derivation of the above statement.

Hope this helps
