Question

How many moles is 4X1023 atoms Ne?​

Answer 1

Answer:

0.66 moles

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

We have

$n = \frac{4 \times {10}^{23} }{6.02 \times {10}^{23} } = \frac{4}{6.02} \\ = 0.664451...$

We have the final answer as

0.66 moles
