Answer:

4 moles

Explanation:

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

[tex]n = \frac{N}{L} \\[/tex]

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

[tex]n = \frac{2.4 \times {10}^{24} }{6.02 \times {10}^{23} } \\ = 3.986710...[/tex]

We have the final answer as

4 moles

Hope this helps you

The number of moles of SO₃ contained in this chemical compound with the given number of elementary entities (2.4 × 10²⁴) is equal to: C. 4.0.

How to calculate number of moles?

In Chemistry, the number of moles of SO₃ contained in this chemical compound with the given number of elementary entities, we would use the following formula:

n = N/NA

where:

  • n is the the number of moles.
  • NA is Avogadro constant.
  • N is the number of elementary entities.

Scientific data:

  • Avogadro's number = 6.02 × 10²³.
  • Number of elementary entities = 2.4 × 10²⁴.

Substituting the given parameters into the formula, we have;

n = 2.4 × 10²⁴/6.02 × 10²³

n = 3.99 ≈ 4.0 moles.
