9.33 units of NaCl

I did not say molecules because sodium chloride is not a molecule, it is an ionic compound.

Explanation:

To find the number of moles of NaCl we use the Avogadro's number to devise the following reasoning:

if          1 mole of NaCl contains 6.022 × 10²³ units of NaCl

then     X mole of NaCl contains 5.62 × 10²⁴ units of NaCl

X = (1 ×  5.62 × 10²⁴) / 6.022 × 10²³

X = 0.933 × 10

X = 9.33  units of NaCl
