Sagot :
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].
