Answer:

Option D. 6.022 x 10^23 ions

Explanation:

1 mole of a substance contains 6.02x10^23 atoms, molecules or ions from Avogadro's hypothesis.

Therefore, 1 mole of sodium sulfate will also contain 6.02x10^23 atoms, molecules or ions

Answer: 1.204 x 10^24 sodium ions

Explanation: First look a the compound sodium sulfate: Na2SO4

1 mol of compound contains 2 mol sodium ions

Second remember 1 mole is always 1 mol=6.022 x 10^23 ions

(2 mols)*(6.022 x 10^23 ions/mol)

=  1.204 x 10^24 sodium ions
