in 2 moles of CO2 there are around 1.2044 times 10^24 molecules. Each CO2 molecule is made up of 3 atoms so the total number of atoms is approximately 3.6132 times 10^24

Explanation:

The number of entities in a mole is given by the Avogadro constant, N_A, which is approximately 6.022 times10^23 entities per mol. For CO2 the entity is a molecule made up of 3 atoms.

Thus in 2 moles we have around, 2 mol times6.022 times10^23 text{ molecules }mol^-1, which is 1.2044 times 10^24 molecules.

Each CO2 molecule is made up of 3 atoms so the total number of atoms is approximately 3.6132 times 10^24
