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:

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.
