To calculate the number of moles from a given number of atoms, you can use Avogadro's number, which is approximately \(6.022 \times 10^{23}\) atoms per mole. The formula to convert the number of atoms to moles is:
\[
\text{moles} = \frac{\text{number of atoms}}{6.022 \times 10^{23} \text{ atoms/mole}}
\]
### Steps:
1. **Take the number of atoms you have**.
2. **Divide that number by Avogadro's number**.
### Example:
If you have \(1.2044 \times 10^{24}\) atoms:
\[
\text{moles} = \frac{1.2044 \times 10^{24} \text{ atoms}}{6.022 \times 10^{23} \text{ atoms/mole}} \approx 2.000 \text{ moles}
\]
This means that \(1.2044 \times 10^{24}\) atoms is approximately 2 moles.
\[
\text{moles} = \frac{\text{number of atoms}}{6.022 \times 10^{23} \text{ atoms/mole}}
\]
