#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.
