Question

What is the number of moles in each of the following? 6 x 10^22 ions of sodium chloride

Answer 1

`\huge\boxed{\sf n = 0.1 \ moles}`

Step-by-step explanation:

Given Data:

No. of formula units (particles) = 6 × 10²² ions

Avogadro's number =
`N_A` = 6.022 × 10²³

Required:

Number of moles = n = ?

Formula:

`\displaystyle no. \ of \ moles = (no. \ of \ particles )/(N_A)`

Solution:

Putting the givens

`\displaystyle n = (6 * 10^(22))/(6.022 * 10^(23)) \\\\n = 10^(-1) \ moles\\\\\boxed{n = 0.1 \ moles}\\\\\rule[225]{225}{2}`
