How many C atoms are present in 1 mole of CO2

6.02*10²³ atoms.

Explanation:

We know that one mole of carbon dioxide contain one mole carbon atom.

1 mole of C = 6.02*10²³ atoms

The number 6.02 * 10²³ is called Avogadro number and it is the number of atoms in one mole of substance.

1 * 6.02*10²³ number of carbon atoms which is equal to the 6.02*10²³ atoms.
