Question

If you have 4.72 x 10^24 atoms of Carbon, how many moles of Carbon do you have?

Answer 1

Answer:

$7.84\ \text{moles}$

Explanation:

Number of atoms of carbon = $4.72\times 10^{24}$

Avogadro's number = $6.022\times 10^{23}\ \text{mol}^{-1}$

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

$\dfrac{4.72\times 10^{24}}{6.022\times 10^{23}}=7.83792\approx 7.84\ \text{moles}$

The moles of carbon are $7.84\ \text{moles}$.
