Question #fcf3f

Answer 1

`2.107times10^24` carbon atoms

Explanation:

In 1 mole of Carbon (or any substance), there are `color(red)(6.02times 10^23` particles in it. That's the `color(red)("Avogadro's Number"` (`N_A`).

Like, in 1 dozen eggs, there are 12 eggs ,
in 1 mole of a particle, there are `color(red)(6.02times 10^23` particles.

1 dozen eggs or 12 eggs:

`--------`

1 mole atoms or `6.02times10^23` atoms:

So, in `color(blue)(3.5` moles of Carbon atoms, there are `color(red)(6.02times10^23)timescolor(blue)(3.5` atoms.

`=2.107times10^24` atoms of carbon.
