Question #8da6a

Answer 1

`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"`
