Correct answer: C. C₆H₁₂O₆
- A. CH₂O
- B. C₂H₄O₂
- C. C₆H₁₂O₆
- D. C₃H₆O₃
Explanation
A molecule of glucose contains 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms. The molecular formula shows this actual count, C₆H₁₂O₆. The formula CH₂O is its simplified empirical formula.

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.
