Question

How to calculate the number of atoms in 1 mole of CO2?

Answer 1

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
