Question #6f2c6

Answer 1

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`
