1. Avogadro's Number

* Avogadro's number tells us the number of atoms in one mole of a substance. It's approximately 6.022 x 10^23 atoms/mol.

2. Setting Up the Calculation

* We want to convert the given number of carbon atoms to moles. We can do this using a conversion factor based on Avogadro's number.

3. Calculation

(3.49 x 10^22 atoms C) * (1 mol C / 6.022 x 10^23 atoms C) = 0.058 moles C

Therefore, there are approximately 0.058 moles of carbon in 3.49 x 10^22 atoms of carbon.
