Answer:

#N_"A"#

Explanation:

I'm not sure if this is what you wanted to ask, but the answer here is Avogadro's constant.

The idea is that in order to have #1# mole of atoms of neon in a given sample, you need to have #6.022 * 10^(23)# atoms of neon. This is known as Avogadro's constant, #N_"A"#, and is how a mole is defined.

Since you have

#color(blue)(ul(color(black)("1 mole Ne" = 6.022 * 10^(23)color(white)(.)"atoms Ne")))#

and

#color(blue)(ul(color(black)(6.022 * 10^(23)color(white)(.)"atoms Ne" = N_"A" color(white)(.)"atoms Ne")))#

you can say that #1# mole of neon contains #N_"A"# atoms of neon.

#"1 mole Ne" = N_"A" color(white)(.)"atoms Ne"#
