Question

How many moles do you have if you have 8.03 x 1023 atoms of oxygen?

Answer 1

The answer is 1.33 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 we have

`n = \frac{8.03 * {10}^(23) }{6.02 * {10}^(23) } \\ = 1.33388704...`

We have the final answer as

1.33 moles
