7. How many moles are in 18.00 x 1023 particles of AICIZ?

Andrej [43]

Answer:

<h3>The answer is option A</h3>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

$n = \frac{N}{L} \\$

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

$n = \frac{18.0 \times {10}^{23} }{6.02 \times {10}^{23} } = \frac{18}{6.02} \\ = 2.99003322...$

We have the final answer as

<h3>2.99 moles</h3>

Hope this helps you
