Explanation:

It is known that in 1 mole there are $6.023 \times 10^{23}$ atoms or molecules.

It is given that there are $7.2 \times 10^{23}$ carbon molecules. Therefore, calculate the moles as follows.

Number of moles = $\frac{7.2 \times 10^{23} molecules}{6.023 \times 10^{23} molecules/mol}$

= 1.196 mol

Thus, we can conclude that there are 1.196 mol in $7.2 \times 10^{23}$ carbon molecules.
