Answer:

[tex]6.022*10^{22}[/tex]

Explanation:

  • 1 mole of any substance contains Avogadro number of particles i.e,  6.022 × 10^23 particles.
  • number of of particles in n moles of a substance = n*Avogadro number
  • number of moles of Ne in 2.0 g of Ne= 2/20=0.1

[number of moles=given weight/ gram molecular weight]

  • so, number of particles in 2.0 g of Ne = number of particles in 0.1 moles of Ne= 0.1(6.022 × 10^23)

=[tex]6.022*10^{22}[/tex]
