Question

Calculate the number of moles in the following: 2.8 X 10^24 atoms of Cl2

Answer 1

The answer is 4.65 moles

Step-by-step explanation:

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

`n = (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

N = 2.8 × 10²⁴ atoms of Cl2

So we have

`n = \frac{2.8 * {10}^(24) }{6.02 * {10}^(23) } \\ = 4.65116279069...`

We have the final answer as

4.65 moles
