The pair of species having the same percentage of carbon is:
Correct answer: A. CH3COOH and C6H12O6
- A. CH3COOH and C6H12O6
- B. CH3COOH and C2H5OH
- C. HCOOCH3 and C12H22O11
- D. C6H12O6 and C12H22O11
Explanation
Mass number of CH3COOH = (2x12) + (4x1) + (2x16) = 60Percentage of carbon = 24/60 x 100 = 40%Mass number of C6H12O6 = (6x12) + (12x1) + (6x16) = 180percentage of carbon = 72/180 x 100 = 40%Mass number of C2H5OH = (2x12) + (6x1) +16 = 46Percentage of carbon = 24/46 x 100 = 52.17%Mass number of C12H22O11 = (12x12) + (22x1) + (11x16) = 342Percentage of carbon = 144/342 x 100 = 42.1%Since CH3COOH and C6H12O6 have the same percentage of carbon A option is our correct answer.

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.
