Answer:
[tex]5.81 moles[/tex]
Explanation:
One mole of any compound contain [tex]6.023 \times 10^{23}[/tex] molecules.
Hence, one mole of sodium containing atoms [tex]$=6.023 \times 10^{23}#[/tex]
[tex]$3.50 \times 10^ {24} $[/tex] atoms containing moles [tex]$=3.50 \times 10^{24} \times \frac{1}{6.023 \times 10^{23}}$[/tex]
[tex]$=0.581 mol$[/tex]
