How many moles of atoms are present in one mole of CH3COOH molecule?
Correct answer: A. 2 moles of C atoms, 4 moles of H atoms, 2 moles of O atoms
- A. 2 moles of C atoms, 4 moles of H atoms, 2 moles of O atoms
- B. 1 mole of C atoms, 2 moles of H atoms, 1 mole of O atoms
- C. 2 moles of C atoms, 3 moles of H atoms, 2 moles of O atoms
- D. 2 moles each of C, H and O
Explanation
The molecular formula of acetic acid is CH3COOH. This means that there are 2 carbon atoms, 4 hydrogen atoms, and 2 oxygen atoms in one molecule of acetic acid. Therefore, in one mole of acetic acid, there are 2 moles of carbon atoms, 4 moles of hydrogen atoms, and 2 moles of oxygen atoms.

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.
