Question

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

Answer 1

Answer:

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

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:

$\displaystyle no. \ of \ moles = \frac{no. \ of \ particles }{N_A}$

Solution:

Putting the givens

$\displaystyle n = \frac{6 \times 10^{22}}{6.022 \times 10^{23}} \\\\n = 10^{-1} \ moles\\\\\boxed{n = 0.1 \ moles}\\\\\rule[225]{225}{2}$
