To find the number of atoms in a given number of moles, you can use Avogadro's number, which is approximately \(6.022 \times 10^{23}\) atoms/mole.
To calculate the number of atoms in 0.75 moles of copper:
\[
\text{Number of atoms} = \text{moles} \times \text{Avogadro's number}
\]
\[
\text{Number of atoms} = 0.75 \, \text{moles} \times 6.022 \times 10^{23} \, \text{atoms/mole}
\]
\[
\text{Number of atoms} \approx 4.54 \times 10^{23} \, \text{atoms}
\]
Therefore, 0.75 moles of copper is approximately \(4.54 \times 10^{23}\) atoms.
