The correct answer is
6.022 × 1023
6.022 × 1023 is correct.
Avogadro's constant is the number of particles (atoms, molecules or ions) in one mole of a substance.
Its value is 6.022 × 1023 mol−1, the number of atoms in exactly 12 g of carbon-12.
The other values change either the digits (6.222, 6.322) or the power of ten (1033).
