Question

How many moles are in 8.30 X 10 to the power of 23, molecules of CO2?

Answer 1

1.38 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{8.30 * {10}^(23) }{6.02 * {10}^(23) } = (8.3)/(6.02) \\ = 1.3787...`

We have the final answer as

1.38 moles
