$3.0231147 \times {10}^{24}$

#### Explanation:

The number of atoms in a single mole of any substance is defined by Avogadro's Number, a constant which is equal to $6.0221409 \times {10}^{23}$, so there are approximately $6.0221409 \times {10}^{23}$ atoms in a single mole of a substance.

To find the number of atoms in a given amount of substance, simply multiply the amount in moles of the substance by Avogadro's Number:

Number of $C$ atoms $= 5.02 \times 6.0221409 \times {10}^{23} = 3.0231147 \times {10}^{24}$
