To calculate the number of atoms in 0.2 moles of sodium (Na), you can use Avogadro's number, which is approximately 6.022 x 10^23 atoms per mole. Here's the calculation:

Number of atoms = Number of moles × Avogadro's number

Number of atoms = 0.2 moles × 6.022 x 10^23 atoms/mole

Number of atoms = 1.2044 x 10^23 atoms

So, there are approximately 1.2044 x 10^23 sodium atoms in 0.2 moles of sodium.
