Passage / Comprehension

Out of below CORRECT matching is -

Answer:

Solution:

Compound (R): $60 g$ of CH₃COOH (Molar mass = $60 g / m o l$ ) equals 1 mole.

Column-II (2): In 1 mole of CH₃COOH (C₂H₄O₂), the mass of Hydrogen is $4 g$ , so $% H = (\frac{4}{60}) \times 100 = \frac{100}{15} %$ .

Column-III (i): Since there are 2 Carbon atoms per molecule, 1 mole contains $2 \times N_{A}$ Carbon atoms ( $2 N_{A}$ ).

Conclusion: All three parts align, making (D) the correct match.
