One mole of CO2 contains
Correct answer: C. 6.022x10^23 atoms of carbon
- A. 6.022x10^23 atoms of oxygen
- B. 22-gram electrons
- C. 6.022x10^23 atoms of carbon
- D. both b & c
Explanation
A mole is a unit used to express the amount of a substance, and it contains Avogadro's number of entities (atoms, molecules, ions, etc.), which is approximately 6.022x10^23.For CO2 (carbon dioxide), the molecular formula indicates that one mole of CO2 contains one mole of carbon atoms (C) and two moles of oxygen atoms (O). One mole of CO2 contains one mole of carbon atoms, and Avogadro's number (6.022x10^23) represents the number of entities in one mole.

About Fundamental Concepts of Chemistry
Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.
