Question

How many moles of carbon is 1.88 x 1025 carbon atoms?

Answer 1

31.23 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

we have

`n = \frac{1.88 * {10}^(25) }{6.02 * {10}^(23) } \\ = 31.229235...`

We have the final answer as

31.23 moles
