Question

Calculate the number of moles if we were given 9.2 x 10 ^ 23 atom of lead . ( plz show work) (helpme0)

Answer 1

The answer is 1.53 moles

Step-by-step explanation:

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

`</p><p>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 we have

`n = \frac{9.2 * {10}^(23) }{6.02 * {10}^(23) } \\ = 1.52823920...`

We have the final answer as

1.53 moles
