1. ### Break Down the Problem

We need to calculate the mass of 8 moles of sodium (Na) atoms using the molar mass from the periodic table.

2. ### Relevant Concepts

The mass of a substance can be calculated using the formula: $\text{mass} = \text{moles} \times \text{molar mass}$ The molar mass of sodium (Na) is approximately $22.99 \, \text{g/mol}$.

3. ### Analysis and Detail

Using the formula mentioned above, we can substitute the values: $\text{mass} = 8 \, \text{moles} \times 22.99 \, \text{g/mol}$

4. ### Verify and Summarize

Perform the calculation: $\text{mass} = 8 \times 22.99 = 183.92 \, \text{g}$ Rounding this to two decimal places gives $183.9 \, \text{g}$.

Final Answer

The mass of 8 moles of sodium atoms is 183.9 g (Option A).
