Answer:

[tex]7.84\ \text{moles}[/tex]

Explanation:

Number of atoms of carbon = [tex]4.72\times 10^{24}[/tex]

Avogadro's number = [tex]6.022\times 10^{23}\ \text{mol}^{-1}[/tex]

Here we have to divide the number of atoms by the Avogadro's number

[tex]\dfrac{4.72\times 10^{24}}{6.022\times 10^{23}}=7.83792\approx 7.84\ \text{moles}[/tex]

The moles of carbon are [tex]7.84\ \text{moles}[/tex].
