Answer:

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#
