Answer 1

Answer:

7.81 moles of Neon.

Explanation:

From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02×10²³ atoms. This simply means that 1 mole of Neon also contains 6.02×10²³ atoms.

From the above illustration, we can convert 4.7×10²⁴ atoms of Neon to moles. this is illustrated below:

6.02×10²³ atoms = 1 mole

Therefore,

4.7×10²⁴ atoms = (4.7×10²⁴ × 1)/6.02×10²³

4.7×10²⁴ atoms = 7.81 moles

Therefore, 4.7×10²⁴ atoms of Neon is equivalent to 7.81 moles of Neon.
