3.11×1024 atoms.

Explanation:

First, you must convert the grams of carbon to moles of carbon. To do this, you must divide the mass (62.0 g) by the molecular weight of carbon, which is 12.011 g/mol..

62.0 g12.011 g/mol=5.16 moles of carbon

Then, convert moles of carbon to atoms of carbon using Avogadro's constant (6.022×1023 atoms per mole)

5.16 moles×6.022×1023 atoms1 mole=3.11×1024 atoms
