Question

how many atoms in 2 mole of gas of Co2​

Answer 1

Answer:

4E24

Explanation:

The number of entities in a mole is given by the Avogadro constant, NA, which is approximately 6.022×1023 entities per mol. For CO2 the entity is a molecule made up of 3 atoms. Thus in 2 moles we have around, 2mol×6.022×1023 molecules mol−1, which is 1.2044×1024 molecules. I mole of co2 contains only 1 carbon atom.
