Question

An sample of neon gas contains 3.75 × 10 ^ 24 in neon Adam's how many moles of neon atoms are in this sample?

Answer 1

`\huge{ \boxed{6.23 \: \text{moles}}}`

Step-by-step explanation:

To find the number of moles in a substance 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 = 3.75 × 10²⁴ atoms

`\therefore \: n = \frac{3.75 * {10}^(24) }{6.02 * {10}^(23) } \\ = 6.2292`

We have the final answer as;

6.23 moles
