How many moles are there in 8.94*10^24 atoms P?

IgorC [24]

Answer:

<h2>14.85 moles </h2>

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

$n = \frac{8.94 \times {10}^{24} }{6.02 \times {10}^{23} } \\ = 14.850498$

We have the final answer as

<h3>14.85 moles</h3>

Hope this helps you
