To find the number of molecules in 0.450 mol of carbon dioxide (CO₂), we can use Avogadro's number, which is \(6.022 \times 10^{23}\) molecules/mol.
The calculation is as follows:
\[
\text{Number of molecules} = \text{Number of moles} \times \text{Avogadro's number}
\]
\[
\text{Number of molecules} = 0.450 \, \text{mol} \times 6.022 \times 10^{23} \, \text{molecules/mol}
\]
Now calculating this:
\[
\text{Number of molecules} \approx 0.450 \times 6.022 \times 10^{23} \approx 2.71 \times 10^{23}
\]
So, there are approximately \(2.71 \times 10^{23}\) molecules of carbon dioxide in 0.450 mol of CO₂.
