Which one of the following will have the largest number of atoms? (Atomic masses: \( \text{Au} = 197, \text{Na} = 23, \text{Li} = 7, \text{Cl} = 35.5 \))

1. \( 1\text{ g} \) of \( \text{Au}(\text{s}) \)
2. \( 1\text{ g} \) of \( \text{Na}(\text{s}) \)
3. \( 1\text{ g} \) of \( \text{Li}(\text{s}) \)
4. \( 1\text{ g} \) of \( \text{Cl}_2(\text{g}) \)
